RESET
OVERVIEW
When a
RESET
signal is input during normal operation or power-down mode, a hardware reset operation is
initiated and the CPU enters idle mode. Then, when the standard oscillation stabilization interval of 31.3 ms at
4.19 MHz has elapsed, normal system operation resumes.
Regardless of when the
RESET
occurs — during normal operating mode or during a power-down mode — most
hardware register values are set to the reset values described in Table 9-1. The current status of several register
values is, however, always retained when a
RESET
occurs during idle or stop mode; If a
RESET
occurs during
normal operating mode, their values are undefined. Current values that are retained in this case are as follows:
— Carry flag
— Data memory values
— General-purpose registers E, A, L, H, X, W, Z, and Y
