After Reset
The TREDY register is used in real-time clock mode.
Set the PROTECT bit in the TREPRC register to 1 (write enabled) before rewriting the TREDY register.
Set values from 01 to 31 by the BCD code.
When the digit increments from the TREHR register, 1 is added. These bits are used to count the number of the
days (28 to 31) in each month, including February in a leap year, for years from 2000 to 2099.
Read or write to these bits when the BSY bit in the TRESEC register is 0 (data not being updated).
