Description

RX FIFO control

Fields

TRIGGER_LEVEL	Trigger level. When the RX FIFO has more entries than the number of this field, a receiver trigger event is generated. Note: software can configure up to 254 in Mono channel enabled (MODE_CTL.PCM_CH_SET = ‘1’ or ‘2’), up to 253 in Stereo channel enabled (MODE_CTL.PCM_CH_SET = ‘3’).
CLEAR	When ‘1’, the RX FIFO and RX_BUF are cleared/invalidated. Invalidation will last for as long as this field is ‘1’. If a quick clear/invalidation is required, the field should be set to ‘1’ and be followed by a set to ‘0’. If a clear/invalidation is required for an extended time period, the field should be set to ‘1’ during the complete time period.
FREEZE	When ‘1’, hardware writes to the RX FIFO have no effect. Freeze will not advance the RX FIFO write pointer.This field is used only for debugging purposes.
