Timer Capture Registers
Four 8-bit capture timer registers provide both rising- and falling-edge event timing capture on two pins. Capture Timer A is
connected to Pin 0.0, and Capture Timer B is connected to Pin 0.1. These can be used to mark the time at which a rising or falling
event occurs at the two GPIO pins. Each timer will capture 8 bits of the free-running timer into its Capture Timer Data Register if
a rising or falling edge event that matches the specified rising or falling edge condition at the pin. A prescaler allows selection of
the capture timer tick size. Interrupts can be individually enabled for the four capture registers. A block diagram is shown in
Figure 19-1
