After Reset
The TREWK register is used in real-time clock mode.
Set the PROTECT bit in the TREPRC register to 1 (write enabled) before rewriting the TREWK register.
A week is counted by counting from 000b (Sunday) to 110b (Saturday) repeatedly. These bits do not change to
111b. Do not set these bits to 111b.
When the digit increments from the TREHR register, 1 is added.
Read or write to these bits when the BSY bit in the TRESEC register is 0 (data not being updated).
