I2Sx_ATAG field descriptions
Description
This read-only field is reserved and always has the value zero.
AC97 Tag Value.
Writing to this register (by the Core) sets the value of the Tx-Tag in AC97 fixed mode of operation. On a
read, the Core gets the Rx-Tag Value received (in the last frame) from the Codec. If TIF bit in ACNT
register is set, the TAG value is also stored in Rx-FIFO in addition to ATAG register. When the received
Tag value changes, the RXT bit in ISR register is set. Bits ATAG[1:0] convey the Codec -ID. In current
implementation only Primary Codecs are supported. Thus writing value 2'b00 to this field is mandatory.

TMSK
Transmit Mask.
Description
These bits indicate which slot has been masked in the current frame. The Core can write to this register to
control the time slots in which the I²S transmits data. Each bit has info corresponding to the respective
time slot in the frame. Transmit mask bits should not be used in I2S Slave mode of operation. TMSK
register value must be set before enabling Transmission.
0 Valid Time Slot.
1 Time Slot masked (no data transmitted in this time slot).
