SPRS370C–SEPTEMBER 2006–REVISED OCTOBER 2007
The McASP serial port is specifically designed for multichannel audio applications. Its key features are:
Flexible clock and frame sync generation logic and on-chip dividers
Up to sixteen transmit or receive data pins and serializers
Large number of serial data format options, including:
–
TDM Frames with 2 to 32 time slots per frame (periodic) or 1 slot per frame (burst).
–
Time slots of 8,12,16, 20, 24, 28, and 32 bits.
–
First bit delay 0, 1, or 2 clocks.
–
MSB or LSB first bit order.
–
Left- or right-aligned data words within time slots
DIT Mode (optional) with 384-bit Channel Status and 384-bit User Data registers.
Extensive error-checking and mute generation logic
All unused pins GPIO-capable
