count.
T8 and T16 Timer Operation
The T8 timer is a programmable 8-bit counter/timer with two 8-bit capture regis-
ters and two 8-bit load registers. The T16 timer is a programmable 16-bit counter/
timer with one 16-bit capture register pair and one 16-bit load register pair. See
Figure 30. The T8 and T16 counters/timers have two modes of operation:
• The transmit mode is used to generate complex waveforms. There are two
submodes:
– The normal mode can be used in single-pass or modulo-N (repeating)
mode.
– The ping-pong mode is used when the T8 timer counts down, enables the
T16 timer that counts down, enabling T8, and so on, until the mode is
disabled.
• The demodulation mode is used to capture and demodulate complex
waveforms.
