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’
