Capture 1 Falling [7:0]
This register holds the value of the Free-running Timer when the last falling edge occurred on the TCAP1 input. The bits that
are stored here are selected by the Prescale [2:0] bits in the Timer Configuration register. When capture 0 is in 16-bit mode this
register holds the high-order 8 bits of the 16-bit timer from the last Capture 0 falling edge. When Capture 0 is in 16-bit mode this
register will be loaded with high-order 8 bits of the 16-bit timer on TCAP0 falling edge.

These four bits contains the status bits for the four timer captures for the four timer block capture interrupt sources. Writing any
of these bits with 1 clears that interrupt.
Bit [7:4]:
Reserved
Bit 3:
Cap1 Fall Active
0 = No event
1 = A falling edge has occurred on Cap1
Bit 2:
Cap1 Rise Active
0 = No event
1 = A rising edge has occurred on Cap1
Bit 1:
Cap0 Fall Active
0 = No event
1 = A falling edge has occurred on Cap0
Bit 0:
Cap0 Rise Active
0 = No event
1 = A rising edge has occurred on Cap0
Note:
The interrupt status bits must be cleared by firmware to enable subsequent interrupts. This is achieved by writing a ‘1’ to
the corresponding Interrupt status bit.

Prog Interval Timer [7:0]
This register holds the low order-byte of the 12-bit programmable interval timer. Reading this register causes the high-order byte
to be moved into a holding register allowing an automatic read of all 12 bits simultaneously.

Prog Internal Timer [11:8]
This register holds the high order nibble of the 12-bit programmable interval timer. Reading this register returns the high order
nibble of the 12-bit timer at the instant that the low order byte was last read.
