Status Flag Register
The Status Flag Register STATF bits will be set by HI-3111 when the
corresponding related events described below occur. Unlike the Interrupt Flag
Register, reading this register will NOT clear all bits. These bits are reset
automatically by HI-3111 when the described status for each bit changes (e.g.
if TXMTY is set and a message is loaded to the transmit FIFO, TXMTY will be
automatically cleared by HI-3111).

BIT
FUNCTION
0
RXFFULL
–
Receive FIFO full.
This bit is set when the receive FIFO is full.
1
RXFMTY
–
Receive FIFO empty.
This bit is set when the receive FIFO is empty. This is the
default following reset.
2
BUSOFF
–
Busoff indicator.
This bit is set when the device enters bus-off state.
3
ERRP
- Error passive indicator.
This bit is set when the device enters error passive mode.
4
ERRW
- Error warning flag.
This bit is set when 96
≤
(TEC or REC)
≤
127.
5
TXHISF
- Transmit history FIFO full.
This bit is set when the transmit history FIFO is full. Up to
eight messages can be stored in the transmit history FIFO
(Note: a user generated message tag and a time tag are
stored with each message).
6
TXFULL
- Transmit FIFO is full.
This bit is set when the transmit FIFO is full.
7
TXMTY
- Transmit FIFO is empty.
This bit is set when the transmit FIFO is empty. This is the
default following Reset.
