4.11.8 Setting Up a One-Shot Pulse Output Using Timer 5

In this example, timer 5 outputs a one-shot pulse. The pulse width is two clock

cycles.

To set up the output port:

Set the P4MD2 bit of the port 4 output mode register (P4MD) to 1 (selecting the

TM5IOA pin) and set the P4DIR2 bit of the port 4 I/O control register (P4DIR)

to 1 (selecting output direction). This step selects the TM5OA pin (P42) as the

timer output port.

P4MD (example) x’00FFF8’
P2DIR (example) x’00FFE4’
