Timer Programming Model

The timer programming model consists of a 24-bit counter, a 24-bit read/write Timer
Control and Status Register (TCSR), a 24-bit write-only Timer Load Register (TLR), a
24-bit read/write Timer Compare Register (TCPR), and a 24-bit read-only Timer Count
Register (TCR). The timers are functionally identical. Figure 9-6 shows the timer
programming model.
