The TREMIN register is always compared with the TRESEC register, and the CMIF bit in the TREIFR register
is set to 1 (interrupt requested) when the values of both the registers match. When the CMIE bit in the TREIER
register is 1 (compare match interrupt enabled), an interrupt request is generated.
Write to the TREMIN register when the RUN bit in the TRECR register is 0 (count stops).
Set the PROTECT bit in the TREPRC register to 1 (write enabled) before rewriting the TREMIN register.
Set values from 00 to 59 by the BCD code.
When the digit increments from the TRESEC register, 1 is added.
Read or write to these bits when the BSY bit in the TRESEC register is 0 (data not being updated).
