16.1.2 Timer Capture
Cypress enCoRe II has two 8-bit captures. Each capture has separate registers for the rising and falling time. The two eight bit captures
can be configured as a single 16-bit capture. When configured, the capture 1 registers hold the high order byte of the 16-bit timer
capture value. Each of the four capture registers may be programmed to generate an interrupt when it is loaded.

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 is 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
