(4) Real-time counter control register 2 (RTCC2)

Symbol
Note RCLOE0 and RCLOE2 must not be enabled at the same time.
Cautions 1.
Remark f
The RTCC2 register is an 8-bit register that is used to control the interval interrupt function and the RTCDIV pin.
RTCC2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

Change ICT2, ICT1, and ICT0 when RINTE = 0.
When the output from RTCDIV pin is stopped, the output continues after a maximum of two
clocks of f
immediately after entering the high level, a pulse of at least one clock width of f
generated.
After the real-time counter starts operating, the output width of the RTCDIV pin may be
shorter than as set during the first interval period.
