Functional Description

T16_Enable

This field enables T16 when set to 1.

Single/Modulo-N

In TRANSMIT mode, when set to 0, the counter reloads the initial value when it reaches

the terminal count. When set to 1, the counter stops when the terminal count is reached.

In DEMODULATION mode, when set to 0, T16 captures and reloads on detection of all

the edges. When set to 1, T16 captures and detects on the first edge but ignores the subse-

quent edges. For details, see T16 DEMODULATION Mode on page 41.

Time_Out

This bit is set when T16 times out (terminal count reached). To reset the bit, write a 1 to

this location.

T16_Clock

This bit defines the frequency of the input signal to Counter/Timer16.

Capture_INT_Mask

This bit is set to allow an interrupt when data is captured into LO16 and HI16.

Counter_INT_Mask

Set this bit to allow an interrupt when T16 times out.
