FIFO_NEAR_OVFL_ST , IO, Address 0x7F[7] (Read Only)
Latched status for the audio FIFO near overflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_OVFL_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_NEAR_OVFL_ST
0 (default)
1
FIFO_UNDERFLO_ST , IO, Address 0x7F[6] (Read Only)
Latched status for the sudio FIFO underflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_UNDERFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_UNDERFLO_ST
0 (default)
1
FIFO_OVERFLO_ST , IO, Address 0x7F[5] (Read Only)
Latched status for the audio FIFO overflow interrupt. Once set, this bit will remain high until the interrupt is cleared via
FIFO_OVERFLO_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
FIFO_OVERFLO_ST
0 (default)
1
CTS_PASS_THRSH_ST , IO, Address 0x7F[4] (Read Only)
Latched status for the ACR CTS value exceed threshold interrupt. Once set, this bit will remain high until the interrupt is cleared via
CTS_PASS_THRSH_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
CTS_PASS_THRSH_ST
0 (default)
1
CHANGE_N_ST , IO, Address 0x7F[3] (Read Only)
Latched status for the ACR N value changed interrupt. Once set, this bit will remain high until the interrupt is cleared via
CHANGE_N_CLR. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
CHANGE_N_ST
0 (default)
1
PACKET_ERROR_ST , IO, Address 0x7F[2] (Read Only)
Latched status for the packet error interrupt. Once set, this bit will remain high until the interrupt is cleared via PACKET_ERROR_CLR.
This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
Function
PACKET_ERROR_ST
0 (default)
1
