Caution:
PRES—Prescale value
The timer input clock is divided by 2
prescaler is reset each time the Timer is disabled. This reset ensures proper clock division
each time the Timer is restarted.
TMODE—Timer mode
This field along with the TMODEHI bit in TxCTL0 register determines the operating
mode of the timer. TMODEHI is the most significant bit of the Timer mode selection
value. The entire operating mode bits are expressed as {TMODEHI, TMODE[2:0]}. The
TMODEHI is bit 7 of the TxCTL0 register while TMODE[2:0] is the lower 3 bits of the
TxCTL1 register.
When the Timer Output alternate function TxOUT on a GPIO port pin is enabled,
TxOUT changes to whatever state the TPOL bit is in.The timer does not need to be en-
abled for that to happen. Also, the Port data direction sub register is not needed to be
set to output on TxOUT. Changing the TPOL bit with the timer enabled and running
does not immediately change the TxOUT.
CAPTURE RESTART mode
0 = Count is captured on the rising edge of the Timer Input signal.
1 = Count is captured on the falling edge of the Timer Input signal.
COMPARATOR COUNTER mode
When the timer is disabled, the Timer Output signal is set to the value of this bit.
When the timer is enabled, the Timer Output signal is complemented upon timer
Reload. Also:
0 = Count is captured on the rising edge of the comparator output.
1 = Count is captured on the falling edge of the comparator output.
000 = Divide by 1
001 = Divide by 2
010 = Divide by 4
011 = Divide by 8
100 = Divide by 16
101 = Divide by 32
110 = Divide by 64
111 = Divide by 128
0000 = ONE-SHOT mode
0001 = CONTINUOUS mode
0010 = COUNTER mode
0011 = PWM SINGLE OUTPUT mode
0100 = CAPTURE mode
0101 = COMPARE mode
0110 = GATED mode
0111 = CAPTURE/COMPARE mode
