A reset caused by the watchdog timer can also be of either of two types: a power-on reset or a
manual reset.
When the MRES pin* is used, MRES pin* input must be enabled by setting the MRESE bit to 1 in
SYSCR.
Note:* Supported only by the H8S/2218 Group.
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 initialized,
2. The reset exception handling vector address is read and transferred to the PC, and program
Note: * Supported only by the H8S/2218 Group.
Figures 4.1 and 4.2 show examples of the reset sequence.
