General-Purpose Timer Units
13.1.1 Key Features
Each general-purpose 16-bit timer unit has the following features:
13.2 General-Purpose Timer Units
The general-purpose timer units provide the following features:
13.3 General-Purpose Timer Programming Model
The following features are programmable through the timer registers, shown in Table 13-1:
13-2
• Maximum period of 4.97 seconds at 54 MHz
• 18.5-nS resolution at 54 MHz
• Programmable sources for the clock input, including external clock
• Input-capture capability with programmable trigger edge on input pin
• Output-compare with programmable mode for the output pin
• Free run and restart modes
• Maskable interrupts on input capture or reference-compare
• Each timer can be programmed to count and compare to a reference value stored in
• System bus clock can be divided by 16 or 1. This clock is input to the prescaler.
• TIN is fed directly into the 8-bit prescaler. The maximum value of TIN is 1/5 of
• The 8-bit prescaler clock divides the clocking source and is user-programmable
• Programmed events generate interrupts.
• The timer output signal (TOUT) can be configured to toggle or pulse on an event.
• Prescaler—The prescaler clock input is selected from CLKIN (divided by 1 or 16)
• Capture mode—Each timer has a 16-bit timer capture register (TCR0 and TCR1)
a register or capture the timer value at an edge detected on TIN.

or from the corresponding timer input, TIN. TIN is synchronized to CLKIN. The
synchronization delay is between two and three CLKIN clocks. The corresponding
TMRn[ICLK] selects the clock input source. A programmable prescaler divides the
clock input by values from 1 to 256. The prescaler is an input to the 16-bit counter.
that latches the counter value when the corresponding input capture edge detector
senses a defined TIN transition. The capture edge bits (TMRn[CE]) select the type
of transition that triggers the capture, sets the timer event register capture event bit,
TERn[CAP], and issues a maskable interrupt.
