Transmit Slip buffer Full Interrupt Status
This Reset-Upon-Read bit indicates whether or not the Transmit Slip
Buffer Full interrupt has occurred since the last read of this register. The
transmit Slip Buffer Full interrupt is declared when the transmit slip buffer
is filled. If the transmit slip buffer is full and a WRITE operation occurs,
then a full frame of data will be deleted, and this interrupt bit will be set to
‘1’.
0 = Indicates that the Transmit Slip Buffer Full interrupt has not occurred
since the last read of this register.
1 = Indicates that the Transmit Slip Buffer Full interrupt has occurred since
the last read of this register.

0
Transmit Slip buffer Empty Interrupt Status
This Reset-Upon-Read bit indicates whether or not the Transmit Slip
Buffer Empty interrupt has occurred since the last read of this register. The
transmit Slip Buffer Empty interrupt is declared when the transmit slip
buffer is emptied. If the transmit slip buffer is emptied and a READ opera-
tion occurs, then a full frame of data will be repeated, and this interrupt bit
will be set to ‘1’.
0 = Indicates that the Transmit Slip Buffer Empty interrupt has not
occurred since the last read of this register.
1 = Indicates that the Transmit Slip Buffer Empty interrupt has occurred
since the last read of this register.

Transmit Slip Buffer Slips Interrupt Status
This Reset-Upon-Read bit indicates whether or not the Transmit Slip
Buffer Slips interrupt has occurred since the last read of this register. The
transmit Slip Buffer Slips interrupt is declared when the transmit slip buffer
is either filled or emptied. This interrupt bit will be set to ‘1’ in either one of
these two conditions:
1. If the transmit slip buffer is emptied and a READ operation occurs,
then a full frame of data will be repeated, and this interrupt bit will be
set to ‘1’.
2. If the transmit slip buffer is full and a WRITE operation occurs, then
a full frame of data will be deleted, and this interrupt bit will be set to
‘1’.
0 = Indicates that the Transmit Slip Buffer Slips interrupt has not occurred
since the last read of this register.
1 = Indicates that the Transmit Slip Buffer Slips interrupt has occurred
since the last read of this register.
NOTE: Users still need to read the Transmit Slip Buffer Empty Interrupt (bit
6 of this register) or the Transmit Slip Buffer Full Interrupts (bit 7 of
this register) to determine whether transmit slip buffer empties or
fills.
