Codec Interface Status
Information
A dedicated status register can inform the software about the current state of the codec
interface. When the codec interface interrupt is unmasked, the status flags reflect the
state of the codec interface interrupt sources. They can be used by the interrupt service
routine to recognize the condition that triggered the interrupt request. When the codec
interface interrupt is masked, the status bits can be polled.
The status bits are set on the active edge of the interrupt source, and are cleared upon
register read.
The codec status register is detailed below.
CODSTS (0xEC06)
TXE
Transmitter empty flag.
TXF
Transmitter full flag.
RXE
Receiver empty flag.
RXF
Receiver full flag.
RXW
Receiver sample ready flag.
TOV
Transmit FIFO overrun.
ROV
Receive FIFO overrun.
