Call Conditionally
If the specified conditions are met, control is passed to
the pma. Not all combinations of conditions are mean-
ingful.

Call Conditionally With Optional Delay
If the specified conditions are met, control is passed to
the pma. Not all combinations of conditions are mean-
ingful.
If you specify a delayed branch (CCD), the next two in-
struction words (two 1-word instructions or one 2-word
instruction) are fetched and executed before the call.
CLRC control bit
√ √
Clear Control Bit
Set the specified control bit to a logic 0. Maskable inter-
rupts are enabled immediately after the CLRC instruc-
tion executes.

Complement Accumulator
Complement the contents of the accumulator (1s com-
plement).

Compare Auxiliary Register With AR0
Compare the contents of the current auxiliary register
to AR0, based on the following cases:
If CM = 00
2
, test whether AR(ARP) = AR0.
If CM = 01
2
, test whether AR(ARP) < AR0.
If CM = 10
2
, test whether AR(ARP) > AR0.
If CM = 11
2
, test whether AR(ARP) ≠ AR0.
If the result is true, load a 1 into the TC status bit; other-
wise, load a 0 into the TC bit. The comparison does not
affect the tested registers.
TMS320C5x devices: Compare the contents of the
auxiliary register with the ARCR.
