Power-On Reset by WDT: When a setting is made for a power-on reset to be generated in the
WDT’s watchdog timer mode, and the WDT’s TCNT overflows, the LSI becomes to be a power-
on reset state.
The pin function controller (PFC) registers and I/O port registers are not initialized by the reset
signal generated by the WDT (these registers are initialized only by a power-on reset from outside
of the chip).
If reset caused by the input signal at the RES pin and a reset caused by WDT overflow occur
simultaneously, the RES pin reset has priority, and the WOVF bit in RSTCSR is cleared to 0.
When WDT-initiated power-on reset processing is started, the CPU operates as follows:
1. The initial value (execution start address) of the program counter (PC) is fetched from the
2. The initial value of the stack pointer (SP) is fetched from the exception processing vector table.
3. The vector base register (VBR) is cleared to H'00000000 and the interrupt mask bits (I3-I0) of
4. The values fetched from the exception processing vector table are set in the PC and SP, then
5.2.3
When the RES pin is high and the MRES pin is driven low, the LSI enters a manual reset state. To
reliably reset the LSI, the MRES pin should be kept at low for at least the duration of the
oscillation settling time that is set in WDT in standby mode (when the clock is halted) or at least
20 t
Registers of on-chip peripheral modules are not initialized. When the LSI enters manual reset
status in the middle of a bus cycle, manual reset exception processing does not start until the bus
cycle has ended. Thus, manual resets do not abort bus cycles. However, once MRES is driven low,
hold the low level until the CPU becomes to be a manual reset mode after the bus cycle ends.
(Keep at low level for at least the longest bus cycle). See Appendix B, Pin States, for the status of
individual pins during manual reset mode.
In the manual reset status, manual reset exception processing starts when the MRES pin is first
kept low for a set period of time and then returned to high. The CPU will then operate in the same
procedures as described for power-on resets.
