Section 16 Realtime Clock (RTC)
RMINAR, RHRAR, RWKAR, RDAYAR, and RMONAR registers are checked, and when the
ENB bit is set to 1, the alarm register and the corresponding counter are compared. If all values in
the specified alarm registers and the corresponding counters match, an RTC alarm interrupt is
generated.
The settable range is “01 to 31 in decimal + ENB bit”. If other values are set, correct operation is
not provided. The settable RDAYCNT range differs according to the month and leap year. Please
confirm the correct setting.
Only the ENB bit in RDAYAR is initialized to 0 by a power-on reset, and the other bits are not
initialized. The RDAYAR contents are retained after a manual reset or in standby mode.
16.2.14 Month Alarm Register (RMONAR)
The month alarm register (RMONAR) is an 8-bit read/write alarm register that corresponds to the
BCD-coded month section counter RMONCNT of the RTC. When the ENB bit is set to 1in
RMONAR, the RMONAR value and RMONCNT value are compared. In this way, the RSECAR,
RMINAR, RHRAR, RWKAR, RDAYAR, and RMONAR registers are checked, and when the
ENB bit is set to 1, the alarm register and the corresponding counter are compared. If all values in
the specified alarm registers and the corresponding counters match, an RTC alarm interrupt is
generated.
The settable range is “01 to 12 in decimal + ENB bit”. If other values are set, correct operation is
not provided.
Only the ENB bit in RMONAR is initialized to 0 by a power-on reset, and the other bits are not
initialized. The RMONAR contents are retained after a manual reset or in standby mode.
