(1) 16-bit Free-run Timer
The 16-bit free-run timer consists of a 16-bit up-counter, a control register, and a prescaler. The output of the
timer/counter is used as the base time for the input capture and output compare.
The operating clock for the counter can be selected from four different clocks.
Four internal clocks (
φ/4, φ/16, φ/32, φ/64)
Interrupts can be generated when a counter value overflow or compare match with compare register 0 occurs
(the appropriate mode must be set for a compare match).
The counter can be initialized to 0000H by a reset, software clear, or compare match with compare register 0.
Register details
The count value of the 16-bit free-run timer can be read from this register. The count is cleared to “0000B” by a
reset. Writing to this register sets the timer value. However, only write to the register when the timer is halted
(STOP = “1”). Always use word access.
The 16-bit free-run timer is initialized by the following.
Reset
The clear bit (CLR) of the control status register
A match between the timer/counter value and compare register 0 of the output compare (if the appropriate
mode is set)
