14.6.6

Serial Audio Interrupt Mask Register (SAIMR)

Writing a one to the corresponding bit position in the Interrupt Mask Register enables the
corresponding interrupt signal. All bits are read/write.

Table 14-10

shows the bit layout of SAIMR.

14.6.7

Serial Audio Data Register (SADR)

Writing a 32-bit sample to this register updates the data into the transmit FIFO. Reading this
register flushes a 32-bit sample from the receive FIFO.

Table 14-11

shows the bit layout of SADR.

Figure 14-3

illustrates data flow through the FIFOs and

SADR.
