After Reset
The TREAWK register is used in real-time clock mode.
Write to this register when the BSY bit in the TRESEC register is 0 (data not being updated).
The TREAWK register is compared with the TREWK register when the ENBWK bit is 1 (day-of-the-week
alarm enabled). If the values of both the registers match, the ALIF bit in the TREIFR register is set to 1
(interrupt requested). When the ALIE bit in the TREIFR register is 1 (alarm interrupt enabled), an interrupt
request is generated.
Set 000b (Sunday) to 110b (Saturday).
