The CMX813 decodes the signaling tones for the Motorola Quick Call series, GE groups A, B and C and the tonesets employed by the Zetron, Reach and Plectron 2-tone radio paging systems. It also decodes the tones for Motorola 5/6-tone paging and the EIA, CCIR, ZVEI1 and EEA tonesets used for HSC radio paging and SELCALL. A simple serial interface allows the host µC to specify the individual tone(s), or group of tones, to be decoded from the extensive list held by the CMX813.
When the µC receives an IRQ it examines the STATUS and DECODED TONE ADDRESS Registers to reveal the tone decoded. In 2-tone mode, the CMX813 will report which of the (up to eight) selected tones it has decoded. This report is an 8-bit index number to the tone in the programmed list. For 5/6-tone or HSC groups, the CMX813 will report which tone in the selected system toneset (e.g. CCIR, EIA) has been decoded, as a 4-bit hexadecimal tone value within the selected group.
To allow for cadence measurements, the
IRQ is activated again when the tone is no longer present. A status
value of “No-tone” is returned. The CMX813 is designed to operate over a wide temperature range with a typical operating current of 0.5mA at 2.7Volts. It also has a Zero-Power mode and is available in 16-pin TSSOP (CMX813E4) and 16-pin DIP (CMX813P3) packages.

4. General Description
When the CMX813 detects the start of a tone, it generates an interrupt and reports which tone was detected. At the end of the tone, it will produce an interrupt and report Notone detected. The host micro should measure and interpret the tone lengths and gap lengths according to calling code requirements. The device is not designed for the decoding of multiple tones that are present simultaneously.
In 2-tone mode, the parameters for decoding each tone in the tone table are stored in a decoding ROM, and any one of these tones can be selected for decoding via an 8-bit ROM address. Up to eight 8-bit ROM addresses can be selected by the host micro for decoding. These are held in an internal address RAM which downloads the addresses sequentially to the ROM and retrieves the tone decode parameters and matches these with the received signal to a find tone decode. If a match is found, the CMX813 generates an interrupt and reports the decoded tone table ROM address. The device can therefore decode any number of single or 2-tone pager codes, formed by any combination of up to 8 different frequencies, received in any order.
In 5/6 tone and HSC modes, the tone parameters are stored in ROM in groups of 16 tones in accordance with the various international tonesets (CCIR/ZVEI etc.). Any one of these groups can be selected for decoding at any time. ROM address sequencing is automatic. When any one of the 16 tones in that group is decoded, the device interrupts and reports the group and tone number of the tone (8 bits).
The input amplifier with suitable external components is used to adjust the received signal to the correct amplitude for the decoder. All functions are controlled over a C-BUS serial
µC interface.

5.1.2.3 TONE ADDRESS Register (Hex address $31)
This register is used to load ROM addresses to the internal RAM for decode as described below:
TONE ADDRESS (Bits 7, 6, 5, 4, 3, 2, 1,
and 0)
The parameters (center frequency) for decoding each tone in the tone table are stored in a decoding ROM, and any one of these tones can be selected for decoding via this 8-bit ROM address. The tones table and address allocations are listed in the Application Notes, Section 6.
For a 1-tone or 2-tone system, up to eight ROM addresses can be loaded to the RAM for decode from a chosen ROM page. A FIFO system is used for loading the RAM memory. If more than 8 ROM addresses were loaded to the RAM, only the last 8 entries will be stored.
For the 5/6 tone and HSC tone system, Bits 7, 6, 5, and 4 are used to select a specific tone set (CCIR/ZVEI etc.) for decode. The decode algorithm will search automatically through the sixteen ROM addresses associated with the chosen tone set.
Bits 3, 2, 1, and 0 are not used and should be set to 0.

5.1.4 Read Only Register Description
5.1.4.1 DECODED TONE ADDRESS Register (Hex address $38)
This register is used to send the decoded ROM addresses to the host micro as described below:
DECODED TONE ADDRESS
(Bits 7, 6, 5, 4, 3, 2, 1, and 0)
When a tone is decoded, the CMX813 generates an interrupt and reports the decoded tone table 8-bit ROM address. The tone table and address allocations are listed in the Application Notes, Section 1.6.
For the 1-tone or 2-tone system, the 8-bit ROM address is located either from ROM PAGE 1 or 2.
For the 5/6 tone and HSC tones system, Bits 7, 6, 5, and 4 represent the selected tone set (CCIR/ZVEI etc), Bits 3, 2, 1, and 0 are the 4 bit Hexadecimal tone value within the selected group. This is located in ROM PAGE 3.
5.1.4.2 STATUS Register (Hex address $3F)
This register is used to indicate the status of the device as described below:
(Bits 7, 6 and 5)
Reserved for future use. These will be set to "110" respectively but should be ignored by user's software.
RAM FULL (Bit 4)
After eight tone addresses are loaded to the RAM for tones located in ROM PAGE 1 or 2, this bit is set to ‘1’. A Clear RAM command will reset it to ‘0’.
DECODE STATUS CHANGE
(Bit 3)
When TONE DECODE (Bit 2 of this register) or the decoded 8 bit address in DECODED TONE ADDRESS Register $38 changes state this bit will be set to "1". A “0” indicates no decode status change.
TONE DECODE (Bit 2)
This bit indicates the status of the tone decoder. A "1" indicates a tone has been detected (TONE DECODE) and a "0" indicates the loss of the tone (NOTONE).
TONE DECODE means that a tone has been decoded and its characteristics are as defined by the bandwidth (see CONTROL Register $30, Bits 5, 4, 3 and
2) and the center frequency (see TONE ADDRESS Register $31, Bit 7 to Bit 0). When Bit 7 and Bit 6 in the CONTROL Register $30 are set to "0" the TONE
DECODE Bit 2 will be set to "0". From NOTONE state, identification of a valid tone which is not in the pre-
programmed list (up to eight tones in 1 or 2 tone system and 16 tones in 5/6 tone or HSC) will cause the decoder to move to the TONE DECODE state with the DECODED ROM PAGE address of "00" in Bits 1 and 0; indicating a valid but unrecognized tone. No interrupt is generated.
Loss of tone will cause the NOTONE timer to be started. If loss of tone continues for the duration of the time-out period, then the decoder will move to the NOTONE state and the identification of pre-programmed tones will start again. The time-out period is not user adjustable.
DECODED ROM PAGE
(Bits 1 and 0)
These two bits represent the ROM PAGE where the decoded tone is located.

If the DECODE STATUS CHANGE (Bit 3) of the STATUS Register is ‘1’ or the RAM FULL (Bit 4) of the STATUS Register changes from ‘0’ to ‘1’ then the
IRQ output will be pulled low.
Reading the STATUS register, clears the interrupt (
IRQ output pulled high) and also, clears Bit 3 of the
STATUS Register, if set. A Clear RAM command clears Bit 4 of the STATUS Register, if set. In Zero Power mode, Status Register Bits 7 to 0 are preset to “110x0000” respectively. RAM FULL (Bit 4)
remains undisturbed.
6. Application Notes
6.1 General
The device should be reset first by the command GENERAL RESET $01. The decoder should then be set up according to the desired characteristics. This entails setting the
DECODER BANDWIDTH and select the ROM PAGE in the CONTROL Register $30, also selecting tones in the chosen ROM PAGE by TONE ADDRESS Register $31 (programming the center frequencies of the desired tones).
Up to 8 tones can be programmed either from ROM PAGE 1 or ROM PAGE 2. The RAM memory location 1 is loaded first then incrementally loaded to location 8. Alternatively, a tone group can be selected from ROM PAGE 3.
The decoder is enabled by the CONTROL Register $30. During operation when the device is receiving, the tones are scanned in the sequence of their location; once a
tone is detected, the remaining tones are not checked. When the decoder detects a change in its present state an interrupt will be generated. The change that
occurred can be read from Bit 3 of the STATUS Register $3F if a tone is detected. NOTONE is indicated by Bit 2 of the same register. The ROM PAGE of that tone can be read from Bits 1 and 0 of the same register. The interrupt is cleared by reading the STATUS Register. The decoded tone address can be read from the DECODED TONE ADDRESS Register $38

Figure 3: C-BUS Timing
Notes:
1. Depending on the command, 1 or 2 bytes of COMMAND DATA are transmitted to the peripheral MSB (Bit 7) first, LSB (Bit 0) last. REPLY DATA is read from the peripheral MSB (Bit 7) first, LSB (Bit 0) last.
2. Data is clocked into and out of the peripheral on the rising SERIAL CLOCK edge.
3. Loaded commands are acted upon at the end of each command.
4. To allow for differing µController serial interface formats C-BUS compatible ICs are able to work with either polarity SERIAL CLOCK pulses.
5. These timings are for the latest version of the C-BUS as embodied in the CMX813, and allow faster transfers than the original C-BUS timings given in MX-COM’s Publication Doc. # 20480060.001.
