Voice TX FIFO Empty Interrupt Enable
Voice TX FIFO Full Interrupt Enable
Should be set as ‘0’.
Voice RX FIFO Empty Interrupt Enable
Voice RX FIFO Full Interrupt Enable
Should be set as ‘0’.
Should be set as ‘0’.
Voice TX FIFO Empty Interrupt Source. When EMPTY field in
VTFINTENA register is set to ‘1’ and EMPTY field in VTFINTVAL
register is set to ‘1’, this field is set to ‘1’. Cleared by software.

Should be set as ‘0’.
Selects the specific interface to communicate between voice codec
and external data.
Should be set as ‘0’.
Reserved
This register is used to send mute data from voice decoder to the
external interface. When this field is set to ‘1’, VSPMUT1 and
VSPMUT0 value are transferred to the external interface.
When using 8-bit external interface, 16-bit data transferred from
voice decoder needs to be changed to 8-bit. When this field is set
to ‘1’, corresponding control circuit is initialized.
When using 8-bit external interface such as UART and so on, 16-bit
data transferred from voice decoder needs to be changed to 8-bit.
When this field is set to ‘1’, high 8-bit data of 16-bit data is
transferred first and then low 8-bit data is transferred.
Reserved
Voice TX DMA Done Interrupt Enable
Should be set as ‘0’.
Voice RX DMA Done Interrupt Enable
Should be set as ‘0’.
Voice TX DMA Done Interrupt Source
Should be set as ‘0’.

0: I2S
1: SPI
2: UART0
3: UART1
