PIT Multiplex Bits for Timer Channel 3:0 — These bits select if the corresponding 16-bit timer is connected to
micro time base 1 or 0. If PMUX is modified, the corresponding 16-bit timer is immediately switched to the other
micro time base.
0 The corresponding 16-bit timer counts with micro time base 0.
1 The corresponding 16-bit timer counts with micro time base 1.
PIT Time-out Interrupt Enable Bits for Timer Channel 3:0 — These bits enable an interrupt service request
whenever the time-out flag PTF of the corresponding PIT channel is set. When an interrupt is pending (PTF set)
enabling the interrupt will immediately cause an interrupt. To avoid this, the corresponding PTF flag has to be
cleared first.
0 Interrupt of the corresponding PIT channel is disabled.
1 Interrupt of the corresponding PIT channel is enabled.
