6.16.1 McASP Peripheral Registers Description(s)

Registers for the McASP are summarized in Table 6-44. The registers are accessed through the peripheral configuration port. The receive buffer registers (RBUF) and transmit buffer registers (XBUF) can also be accessed through the DMA port, as listed in Table 6-45

Registers for the McASP Audio FIFO (AFIFO) are summarized in Table 6-46. Note that the AFIFO Write FIFO (WFIFO) and Read FIFO (RFIFO) have independent control and status registers. The AFIFO control registers are accessed through the peripheral configuration port.
