6.12 Power-on reset
The SD6830 incorporates an on-chip power-on reset circuitry which provides internal chip
reset for most power-up situations. The power-on reset circuit and the watchdog timer are
closely related. On power-up the power-on reset circuit is active and watchdog timer is
reset. After the reset time, which is in proportion to the rate of rise of VDD, watchdog timer
begins counting. After the oscillator stabilization time, which is typically 27mS in
F
S YS
= 455KHz, program execution proceeds from reset address (000H).

6.13 Stop mode
The SD6830 support the stop mode to reduce power consumption. This mode is entered
when the STOP instruction is executed during key inputs are not active. Activating any key
inputs (Port D, Port E) the device is awakened from stop mode and restarts to operate from
reset address. When the device is released from stop mode, following module
set to appropriate value in reset routine: PORT G and PORT K.
In stop mode, the oscillator is stopped and the each port state is as follows.
Port C/REM become inactive state. (
for including I.R.LED driver,
after the reset release)
Port G and Port K retain previous state.
