Note:
If D6 of CTR2 Is 1
T16 ignores the subsequent edges in the input signal and continues counting down. A tim-
eout of T8 causes T16 to capture its current value and generate an interrupt if enabled
(CTR2, D2). In this case, T16 does not reload and continues counting. If the D6 bit of
CTR2 is toggled (by writing a 0 then a 1 to it), T16 captures and reloads on the next edge
(rising, falling, or both depending on CTR1, D5; D4), continuing to ignore subsequent
edges.
This T16 mode generally measures mark time, the length of an active carrier signal burst.
If T16 reaches 0, T16 continues counting from
is set, and an interrupt timeout can be generated if enabled (CTR2 D1).
PING-PONG Mode
This operation mode is only valid in TRANSMIT Mode. T8 and T16 must be programmed
in SINGLE-PASS mode (CTR0, D6; CTR2, D6), and PING-PONG mode must be
programmed in CTR1, D3; D2. You can begin the operation by enabling either T8 or T16
(CTR0, D7 or CTR2, D7). For example, if T8 is enabled, T8_OUT is set to this initial
value (CTR1, D1). According to T8_OUT's level, TC8H or TC8L is loaded into T8. After
the terminal count is reached, T8 is disabled, and T16 is enabled. T16_OUT then switches
to its initial value (CTR1, D0), data from TC16H and TC16L is loaded, and T16 starts to
count. After T16 reaches the terminal count, it stops, T8 is enabled again, repeating the
entire cycle. Interrupts can be allowed when T8 or T16 reaches terminal control (CTR0,
D1; CTR2, D1). To stop the ping-pong operation, write 00 to bits D3 and D2 of CTR1. See
Figure
Enabling ping-pong operation while the counter/timers are running might cause intermit-
tent counter/timer function. Disable the counter/timers and reset the status flags before
instituting this operation.
