SR - Channel Status Register (address 0x01) bit description
Description
Transmitter Ready.
This bit, when set, indicates that the TxFIFO is ready to be loaded with at
least one more character. This bit is cleared when the TxFIFO is full or is
above its interrupt threshold level set in the MR registers or TxFIFO interrupt
Fill Level register (TxFIL). Characters loaded in the TxFIFO while the
transmitter is disabled will not be transmitted.
RxFIFO Full.
This bit is set when a character is transferred from the Receive Shift Register
to the receive FIFO, and the transfer causes the FIFO to become full, that is,
all 256 RxFIFO positions are occupied. It is reset when the CPU reads the
RxFIFO and that read leaves one or more empty byte position(s). If a
character is waiting in the receive shift register because the RxFIFO is full,
RxFULL is not reset until the second read of the RxFIFO since the waiting
character is immediately loaded to the RxFIFO.
Receiver Ready.
This bit indicates that a character has been received and is waiting in the
RxFIFO to be read by the CPU. It is set when the character is transferred
from the receive shift register to the RxFIFO and reset when the CPU reads
the RxFIFO, and no more characters are in the RxFIFO.
