Section 4 Exception Handling
4.3.2
When the RES or MRES pin goes low, this LSI enters the reset. To ensure that this LSI is reset,
hold the RES pin low for at least 20 ms at power-up. To reset the chip during operation, hold the
RES or MRES pin low for at least 20 states. When the RES or MRES pin goes high after being
held low for the necessary time, this LSI starts reset exception handling as follows.
1. The internal state of the CPU and the registers of the on-chip peripheral modules are
2. The reset exception handling vector address is read and transferred to the PC, and program
Figures 4.1 shows an example of the reset sequence.
