4.2.1
A reset is the highest-priority exception. When the
chip enters the reset state. A reset initializes the internal state of the CPU and the registers of the
on-chip supporting modules. Reset exception handling begins when the

The chip can also be reset by overflow of the watchdog timer. For details see section 11,
Watchdog Timer.

The internal state of the CPU and the registers of the on-chip supporting modules are
initialized, and the I bit is set to 1 in CCR.
The contents of the reset vector address (H'0000 to H'0003 in advanced mode, H'0000 to
H'0001 in normal mode) are read, and program execution starts from the address indicated in
the vector address.
