8. Bus State Controller (BSC)
Bit 6⎯Compare Match Flag (CMF): This status flag, which indicates that the values of RTCNT
and RTCOR match, is set/cleared under the following conditions:
Bit 6
CMF
0
1
Description
Clear condition: After RTCSR is read when CMF is 1, 0 is written in
CMF.
(initial value)
Set condition: RTCNT = RTCOR. When both RTCNT and RTCOR are
in an initialized state (when values have not been rewritten since
initialization, and RTCNT has not had its value changed due to a count-
up), RTCNT and RTCOR match, as both are H'0000, but in this case
CMF is not set.
Bit 5⎯Compare Match Interrupt Enable (CMIE): Enables or disables an interrupt request
caused by the CMF bit of the RTCSR when CMF is set to 1.
Bit 5
CMIE
0
1
Description
Disables an interrupt request caused by CMF
Enables an interrupt request caused by CMF

Bits 4 to 2⎯Clock Select (CKS2 to CKS0): Select the clock to input to RTCNT from among the
seven types of internal clock obtained from dividing the system clock (φ).
