16.2
16.2.1
The 64-Hz counter (R64CNT) is an 8-bit read-only register that indicates the state of the RTC
divider circuits (RTC prescaler or R64CNT) between 64 Hz and 1 Hz.
R64CNT is reset to H'00 when the RESET bit in RTC control register 2 (RCR2) or the ADJ bit in
RCR2 is set to 1.
R64CNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
Bit 7 is always read as 0.
16.2.2
The second counter (RSECCNT) is an 8-bit read/write register that is used for setting/counting in
the BCD-coded second section of the RTC. The count operation is performed by a carry for each
second of the 64-Hz counter.
The settable range is 00 to 59 in decimal. If other values are set, correct operation is not provided.
When modifying RSECCNT, check that the count operation has been halted with the START bit
in RCR2.
RSECCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
