Counter-Timer Core
The IPC-Timer APB Timer module is a sixteen bit down counter with a selectable pres-caler. Prescale values of 1, 16 and 256 can be selected. The prescaler extends the timer¡¦s range at the expense of precision. The Timer provides two modes of operation that provide a free running value and also periodic interrupts.
The Timer contains several configuration registers that can be written and read by the processor. Two 4-bit prescalers precede a 16-bit counter. The counter can be clocked at either the input clock rate, or a choice of 2 prescaled rates. The counter can be loaded with a value from a preload register. The counter can optionally generate an interrupt.
