Time Seconds Register
When the time counter is enabled, the TSR is read only and increments once a second provided SR[TOF]
or SR[TIF] are not set. The time counter will read as zero when SR[TOF] or SR[TIF] are set. When the
time counter is disabled, the TSR can be read or written. Writing to the TSR when the time counter is
disabled will clear the SR[TOF] and/or the SR[TIF]. Writing to the TSR register with zero is supported, but
not recommended since TSR will read as zero when SR[TIF] or SR[TOF] are set (indicating the time is
invalid).
This read-only field is reserved and always has the value zero.
Time Prescaler Register
When the time counter is enabled, the TPR is read only and increments every 32.768 kHz clock cycle.
The time counter will read as zero when SR[TOF] or SR[TIF] are set. When the time counter is disabled,
the TPR can be read or written. The TSR[TSR] increments when bit 14 of the TPR transitions from a logic
one to a logic zero.
