(17) Prescaler mode register 0 (PRSM0)
Cautions 1.
(a) Alarm interrupt setting examples (RC1ALM, RC1ALH, and RC1ALW setting examples)
The PRSM0 register (8-bit) controls the generation of the real time counter count clock (f
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
Tables 12-4 and 12-5 show setting examples if Sunday is RC1WEEK = 00, Monday is RC1WEEK = 01,
Tuesday is RC1WEEK = 02, ···, and Saturday is RC1WEEK = 06.

After reset : 00H
Do not change the values of the BGCS00 and BGCS01 bits during real time
counteroperation.
Set the PRSM0 register before setting the BGCE0 bit to 1.
Set the PRSM0 and PRSCM0 registers according to the main clock frequency that is used
so as to obtain an f
