Bit 7:
First Edge Hold
The First Edge Hold function applies to all four capture timers.
0 = The time of the most recent edge is held in the Capture Timer Data Register. If multiple edges have occurred since reading
the capture timer, the time for the most recent one will be read
1 = The time of the first occurrence of an edge is held in the Capture Timer Data Register until the data is read. Subsequent
edges are ignored until the Capture Timer Data Register is read.
Bit [6:4]:
8-bit Capture Prescale [2:0]
This field controls which 8 bits of the 16 Free Running Timer are captured when in bit mode
0 0 0 = capture timer[7:0]
0 0 1 = capture timer[8:1]
0 1 0 = capture timer[9:2]
0 1 1 = capture timer[10:3]
1 0 0 = capture timer[11:4]
1 0 1 = capture timer[12:5]
1 1 0 = capture timer[13:6]
1 1 1 = capture timer[14:7]
Bit 3:
Cap0 16-bit Enable
0 = Capture 0 16-bit mode is disabled
1 = Capture 0 16-bit mode is enabled. Capture 1 is disabled and the Capture 1 rising and falling registers are used as an extension
to the Capture 0 registers—extending them to 16 bits
