13.6.2.3 Modulo Mode
When the timer operates in modulo mode the
8-bit counter starts at 0x00 and increments at
each active clock edge. When the counter
reaches the value held in register TxCC the
counter is reset to 0x00 and continues to
increment. The flag TIMIF.TxOVFIF is set on
this event. If the corresponding interrupt mask
bit TxCTL.OVFIM is set, an interrupt request is
generated. The modulo mode can be used for
applications where a period other than 0xFF is
required.

13.6.2.4 Up/down Mode
In the up/down timer mode, the counter
repeatedly starts from 0x00 and counts up until
the value held in TxCC is reached and then the
counter counts down until 0x00 is reached.
This timer mode is used when symmetrical
output pulses are required with a period other
than 0xFF, and therefore allows
implementation of centre-aligned PWM output
applications.
The counter is reset to 0x00 by writing to
TxCTL.CLR.
