MB91460D Series

■ Clock supervisor

❐ Monitors the sub-clock (32 kHz) and the main clock

(4 MHz) , and switches to a recovery clock (CR oscillator,

etc.) when the oscillations stop.

■ Clock modulator

■ Clock monitor

■ Sub-clock calibration

❐ Corrects the real-time clock timer when operating with the 32

kHz or CR oscillator

■ Main oscillator stabilization timer

❐ Generates an interrupt in sub-clock mode after the

stabilization wait time has elapsed on the 23-bit stabilization

wait time counter

■ Sub-oscillator stabilization timer

❐ Generates an interrupt in main clock mode after the

stabilization wait time has elapsed on the 15-bit stabilization

wait time counter
