This read-only field is reserved and always has the value zero.
Time Counter Enable
When time counter is disabled the TSR register and TPR register are writeable, but do not increment.
When time counter is enabled the TSR register and TPR register are not writeable, but increment.

This read-only field is reserved and always has the value zero.
Time Alarm Flag
Time alarm flag is set when the TAR[TAR] equals the TSR[TSR] and the TSR[TSR] increments. This bit is
cleared by writing the TAR register.
0
1
Time Overflow Flag
Time overflow flag is set when the time counter is enabled and overflows. The TSR and TPR do not
increment and read as zero when this bit is set. This bit is cleared by writing the TSR register when the
time counter is disabled.
0
1
Time Invalid Flag
The time invalid flag is set on VBAT POR or software reset. The TSR and TPR do not increment and read
as zero when this bit is set. This bit is cleared by writing the TSR register when the time counter is
disabled.
