T8 Demodulation Mode
Program TC8L and TC8H to FFh. After T8 is enabled, when the first edge (rising,
falling, or both depending on CTR1, D5; D4) is detected, it starts to count down.
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is
detected during counting, the current value of T8 is complemented and put into
one of the capture registers. If it is a positive edge, data is put into LO8, if negative
edge, HI8. One of the edge detect status bits (CTR1, D1; D0) is set, and an inter-
rupt can be generated if enabled (CTR0, D2). Meanwhile, T8 is loaded with FFh
and starts counting again. If T8 reaches 0, the timeout status bit (CTR0, D5) is set,
an interrupt can be generated if enabled (CTR0, D1), and T8 continues counting
from FFh (see Figure 19 and Figure 20).
