NAME AND DESCRIPTION
RNE
HSR.3
Receive FIFO Not Empty. Set when the receive 64-byte
FIFO has at least one byte available for a read. The setting of
this bit prompts the user to read the RHIR register for details.
THALF
HSR.2
Transmit FIFO Half Empty. Set when the transmit 64 byte
FIFO empties beyond the half way point. The setting of this
bit prompts the user to read the THIR register for details.
TNF
HSR.1
Transmit FIFO Not Full. Set when the transmit 64-byte
FIFO has at least one byte available. The setting of this bit
prompts the user to read the THIR register for details.
TMEND
HSR.0
Transmit Message End. Set when the transmit HDLC
controller has finished sending a message. The setting of this
bit prompts the user to read the THIR register for details.
NOTE:
The RBOC, RPE, RPS, and TMEND bits are latched and will be cleared when read.
