Internal Reset Control
There is an internal reset control register, RSTC, which is used to provide a reset when the device
operates abnormally due to the environmental noise interference. If the content of the RSTC register
is set to any value other than 01010101B or 10101010B, it will reset the device after 2~3 f
LIRC
clock
cycles. After power on the register will have a value of 01010101B.

: Reset function control
01010101: No operation
10101010: No operation
Other values: Reset MCU
If these bits are changed due to adverse environmental conditions, the microcontroller
will be reset. The reset operation will be activated after 2~3 LIRC clock cycles and the
RSTF bit in the RSTFC register will be set to 1.

This bit is set to 1 by the RSTC control register software reset and cleared by the
application program. Note that this bit can only be cleared to 0 by the application
program.
