Register Mapping

Register Mapping discusses the registers of the CY8CMBR3102, CY8CMBR3106S, CY8CMBR3108, CY8CMBR3110, CY8CMBR3116 CapSense® Express™ Controllers. It lists all the registers in mapping tables, in address order.

1.1 Maneuvering Around the Registers

For ease-of-use, this chapter is formatted so that there is one re gister p er page, although some re gisters use two pages. On each page, from top to bottom, there are four sections:

1. Register name and address (from lowest to highest).

2. Register table showing the bit organization.

3. Written description of register specifics or links to additional register information.

4. Detailed register bit descriptions.

1.2 Register Conventions

The following table lists the register conventions.

Convention Example Description

‘x’ in a register name ACBxxCR1 Multiple instances/address ranges of the same register R R Read register or bit(s) W W Write register or bit(s) NA NA Reserved None None Not defined register MSB PROX_TOUCH_TH0 MSB Most significant byte of the register register LSB PROX_TOUCH_TH0 LSB Least significant byte of the register

- - Byte does not exist

1.3 Endianness

All registers mentioned in the document are little endian.

1.4 Factory Default Values

The following tables list the registers applicable to each device and provide the factory default values for configuration regi sters.

1.5 Register Map

The CY8CMBR3xxx family features an I2C configurable register map. The CY8CMBR3xxx registers are divided into three categories, as the following table shows.

CY8CMBR3xxx Registers

gory

Configuration

Registers

Command

Registers

Status Registers 0x88-0xFB These are read only registers and indicate the status of command execution, system

The CY8CMBR3xxx devices feature a safe register map update mechanism to overcome configuration data corruption, which can occur due to power failure during execution of “Save” command or any other spurious events.

If the configuration data is corrupted when the device is saving data, on the next reset, the devices reconfigure themselves to the last known valid configuration. If there is no valid con figuratio n saved by u s er, the devices load the factory default config uration.

The following table provides all registers available in CY8CMBR3xxx family. Refer to Factory Default Values on page 6 for details on which register is applicable to which device.

Description

0x00-0x7E These registers contain the configuration data for the CY8CMBR3xxx controllers. A host

can write into these registers and save the data to non-volatile memory by writing to

CTRL_CMD command register . Note that the new configuration takes effect only after the

configuration is saved to non-volatile memory and the device is reset.
