BASIC FUNCTION BLOCKS

The M37735MHLXXXHP has the same functions as the
M37735MHBXXXFP except for the package and the reset circuit.
Refer to the section on the M37735MHBXXXFP.

RESET CIRCUIT

The microcomputer is released from the reset state when the RESET
pin is returned to “H” level after holding it at “L” level with the power
source voltage at 2.7 – 5.5 V. Program execution starts at the address
formed by setting address A
of address FFFF
Figure 1 shows an example of a reset circuit. When the stabilized
clock is input from the external to the main-clock oscillation circuit,
the reset input voltage must be 0.55 V or less when the power source
voltage reaches 2.7 V. When a resonator/oscillator is connected to
the main-clock oscillation circuit, change the reset input voltage from
“L” to “H” after the main-clock oscillation is fully stabilized.
The status of the internal registers during reset is the same as the
M37735MHBXXXFP’s.
RESET

Note. In this case, stabilized clock is input from the external to the main-clock oscillation circuit. Perform careful evalvation at the system design level before using.

Notes 1. This applies when the main clock external input selection bit = “1”, the main clock division selection bit = “0”, and the signal output stop
2. This applies when the main clock external input selection bit = “1” and the system clock stop bit at wait state = “1”.
3. This applies when CPU and the clock timer are operating with the sub clock (32.768 kHz) selected as the system clock.
