6.1.2 Type 2 Timer/Counter I/O Pins
Each of the three timer/counters, typically, has a pair of pins associated with it to support the enhanced input/output functionality. The pair
of pins are referred to as the primary and secondary pins and are designated the symbols T2P0 and T2PB0, respectively. Because there
are three Type 2 timers, the pairs are referred to as follows: T2P0, T2PB0; T2P1; T2P2, T2PB2 (secondary pin is not available for timer 1).
A slightly different naming convention is also used for the primary and secondary pins, as shown by the following:
Timer 0: T2P0, T2PB0 = T0, T0B
Timer 1: T2P1 = T1 (no secondary output on T1B)
Timer 2: T2P2, T2PB2 = T2, T2B
To generalize, T2Px, T2PBx = Tx, TxB where x = 0, 1, 2.
Both naming conventions are commonly used for the MAXQ microcontrollers.

PORT PIN
FUNCTION
Timer 0 Input/Output—T0 (T2P0) 12 P0.3/ADCCTL
Digital GPIO and ADC Control Input. As T0 this pin is the primary
timer/PWM0 input or output. As ADCCTL this user-programmable rising
or falling edge controls the SAR ADC sampling instant and start of con-
version. Optionally, the other edge can be used to enable the ADC and
begin acquiring prior to sampling.
Timer 0 Secondary Output—T0B (T2PB0) 13 P0.4
Digital GPIO, Timer 0 I/O, and Comparator Output. As T0B this pin is the
secondary timer/PWM1 input or output. As CMPO this pin is the output of
the digital comparator for the lowpass filter.
Timer 1 Input/Output—T1 (T2P1)* 14 P0.5
Digital GPIO and Timer 1 I/O. As T1 this pin is the primary timer/PWM2
input or output.
Timer 2 Input/Output—T2 (T2P2) 15 P0.6
Digital GPIO and Timer 2 I/O. As T2 this pin is the primary timer/PWM2
input or output.
Timer 2 Secondary Output—T2B (T2PB2) 16 P0.7
Digital GPIO and Timer 2 I/O. As T2B this pin is the secondary
timer/PWM2 input or output.
*The secondary pin is not supported for timer 1 in the MAXQ7667.
