Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Compare Match Flag
The CMF status flag indicates that the values of
RTCNT and RTCOR match.
0: The values of RTCNT and RTCOR do not
1: The values of RTCNT and RTCOR match.
Note: * Contents don’t change when 1 is written to
Compare Match Interrupt Enable
Enables or disables an interrupt request caused
when the CMF of RTCSR is set to 1. Do not set
this bit to 1 when using auto-refresh.
0: Disables an interrupt request caused by CMF
1: Enables an interrupt request caused by CMF
Clock Select Bits
Select the clock input to RTCNT. The source clock
is the external bus clock (CKIO). The RTCNT
count clock is CKIO divided by the specified ratio.
RTCOR should be set before setting CKS2 to
CKS0.
000: Disables clock input
001: Bus clock (CKIO)/4
010: CKIO/16
011: CKIO/64
