Description
Clock Select Bits
These bits select the input clock for RTCNT. The source
clock is the off-chip bus clock (CKIO). The RTCNT count
clock is obtained by dividing CKIO by the specified
factor.
000: Clock input disabled
001: CKIO/4
010: CKIO/16
011: CKIO/64
100: CKIO/256
101: CKIO/1024
110: CKIO/2048
111: CKIO/4096
Refresh Count Overflow Flag
Status flag that indicates that the number of refresh
cycles in RFCR has exceeded the number specified by
the LMTS bit in RTCSR.
0: RFCR has not overflowed the count limit indicated by
[Clearing condition]
When 0 is written to OVF
1: RFCR has overflowed the count limit specified by
[Setting condition]
When RFCR overflows the count limit specified by
LMTS*
Refresh Count Overflow Interrupt Enable
Controls whether or not an interrupt request is enabled
when the OVF bit is set to 1 in RTCSR.
0: Interrupt requests by OVF disabled
1: Interrupt requests by OVF enabled
Refresh Count Overflow Limit Select
Specifies the count limit to be compared with the RFCR
value. If the RFCR value exceeds the value specified by
LMTS, the OVF bit is set.
0: Count limit is 1024
1: Count limit is 512
