12.2.12 Cautions on Accessing Refresh Control Related Registers
RFCR, RTCSR, RTCNT, and RTCOR require that a specific code be appended to the data when it
is written to prevent data from being mistakenly overwritten by program overruns or other write
operations (figure 12.4). Perform reads and writes using the following methods:
1. Writing to RFCR, RTCSR, RTCNT, and RTCOR
2. Reading from RFCR, RTCSR, RTCNT, and RTCOR
RTCSR, RTCNT,
When writing to RFCR, RTCSR, RTCNT, and RTCOR, use only word transfer instructions.
You cannot write with byte transfer instructions.
When writing to RTCNT, RTCSR, or RTCOR, place B'10100101 in the upper byte and the
write data in the lower byte. When writing to RFCR, place B'101001 in the top 6 bits and the
write data in the remaining bits, as shown in figure 12.4.
When reading from RFCR, RTCSR, RTCNT, and RTCOR, carry out reads with 16-bit width.
0 is read out from undefined bit sections.
