Bit Field Name
7:0 _I2SDAT[7:0]
Reset
0x00
R/W Description
R/W Data register low byte.
If the I2SDATL register is not written between two
writes of the I2SDATH register, the low byte of the
TX register will be cleared.
Bit Field Name
7:0 _I2SDAT[15:8]
0xDF43: I2SDATH – I2S Data High Byte
Reset
R/W Description
0x00
R/W Data register high byte.
When this register is read, the RXIRQ bit of the
I2SSTAT register is cleared and the RX buffer is
considered empty. When this register is written, the
TXIRQ bit of the I2SSTAT register is cleared and the
TX buffer is considered full.
Bit Field Name
7:0 _WCNT[7:0]
0xDF44: I2SWCNT – I2S Word Count Register
Reset
R/W Description
0x00
R/W This register contains the 8 low order bits of the 10-
bit nternal word counter at the time the last trigger
specified by I2SCFG1.TRIGNUM occurred. If this
register is written (any value), the value of the
internal word counter is copied into this register and
the internal word counter is cleared.
Refer to section 13.14.11 for details about how to
use this register.

Reset
R/W Description
0
R/W Tx buffer underflow. This bit must be cleared by
software.
0
R/W Rx buffer overflow. This bit must be cleared by
software.
0
R Left (=0) or right (=1) channel should be placed in
transmit buffer.
0
R Left (=0) or right (=1) channel currently in receive
buffer.
0
R/W Interrupt flag indicating that a tx interrupt request has
not been serviced. This bit is cleared by hardware
H0 _{when the I2SDATH register is written.}
0
R/W Interrupt flag indicating that an rx interrupt request
has not been serviced. This is cleared by hardware
H0 _{when the I2SDATH register is read.}
00
