(b) Release by reset signal generation
Subsystem clock
(XT1 oscillation)
When the reset signal is generated, HALT mode is released, and then, as in the case with a normal reset
operation, the program is executed after branching to the reset vector address.
Notes 1. The 78K0/KB2 is not provided with a subsystem clock.
