Description
7 RXACT
Read/Write
Receive Active. Set to 1 whenever a pulse or pulse-train is
detected by the receiver. If a 1 is written into the bit
position, the bit is cleared and the receiver is de-actived.
When this bit is set, the receiver samples the IR input
continuously at the programmed baud rate and transfers
the data to the receiver FIFO.
6 RX_PD
Read Only
Set to 1 whenever a pulse or pulse-train (modulated pulse)
is detected by the receiver. Can be used by the sofware to
detect idle condition Cleared Upon Read.
