Timer Capture Registers
Four 8-bit timer capture 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 GPIO events
occur. Each timer will capture 8 bits of the free-running timer into a data register. 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.
Each of the four capture registers can be individually enabled to provide interrupts.
The four capture data registers are read-only, and are shown in Figure 19-2 through Figure 19-5.
Three prescaler bits allow the capture timer clock rate to be selected among 5 choices, as shown in Table 19-1 below. The Capture
Status Register (Figure 19-6) contains the prescale settings and the interrupt enables for the 4 possible events. Setting an enable
bit allows for an interrupt from the respective timer event. Note that both Capture A events share a common interrupt request, as
do the two Capture B events. In addition to the event enables, the main Capture Interrupt Enables in the Global Interrupt Enable
register (Section 21.0) must be set to activate a capture interrupt.
The Capture Status Register (Figure 19-7) records the occurrence of any rising or falling edges on the capture GPIO pins. Bits
in this register are cleared by reading the corresponding data register.
