The maximum input clock is the system bus clock
Four 16-bit programmable timers
Two timers cascaded internally or externally to form a 32-bit timer
One timer cascaded internally or externally to form a 64-bit timer
Maximum period of ~412.3 seconds (at 167-MHz bus clock and prescaler = 256) for 16-bit timer
Maximum period of ~12.8825 seconds (at 167-MHz bus clock and prescaler = 256) for 32-bit timer
Maximum period of thousands of years (at 167-MHz bus clock and prescaler = 256) for 64-bit
timer
3-nanosecond timer resolution (at 167-MHz bus clock and no prescaler)
Resolution and maximum period can be traded off by selecting prescaler divisor
Three programmable input clock sources for the timer prescalers
