SPRS268E –MAY 2005 –REVISED JANUARY 2007

The three McASPs on C672x have different configurations (see Table 4-17). NOTE: McASP2 is not available on the C6722.

Table 4-17. McASP Configurations on C672x DSP

McASP	DIT	CLOCK PINS	DATA PINS	COMMENTS
McASP0	No	AHCLKX0/AHCLKX2, ACLKX0, AFSX0	Up to 16	AHCLKX0/AHCLKX2 share pin.
		AHCLKR0/AHCLKR1, ACLKR0, AFSR0		AHCLKR0/AHCLKR1 share pin.
McASP1	No	AHCLKX1, ACLKX1, AFSX1, ACLKR1, AFSR1	Up to 6	AHCLKR0/AHCLKR1 share pin
McASP2	Yes	ACLKX2, AFSX2, AHCLKR2, ACLKR2, AFSR2	Up to 2	Full functionality on C6727. On C6726,
		(Only available on the C6727.)		functions only as DIT since only
				AHCLKX0/AHCLKX2 is available.
				Not available on the C6722.

NOTE: The McASPs do not have dedicated AMUTEINx pins. Instead they can select one of the pins listed in Table 4-19, Table 4-20, and Table 4-21to use as a mute input.
