Real Time Clock (RTC)

(Watch Timer)

facility to correct oscillation deviation

read/write accessible second/minute/

hour registers

can signal interrupts every second/

minute/hour/day

internal clock divider and prescaler pro-

vide exact 1s clock

this clock is based on the 4 MHz oscilla-

tor or if the subclock option is selected on

the 32 kHz subclock

Clock disable

prescaler values are 1E847FH ,

and 4000H for 4MHz and

32.768KHz respectively.

32KHz subclock

+ calibration unit

In RTC mode, the RTC module can be

driven by either 4MHz or 32KHz oscilla-

tor, depending on the configuration.

Additional hardware which allows calibra-

tion of the 32KHz clock based on the

4MHz clock is built in.

This function is only available on

MB91F368GA.
