SAE 81C90/91
Output-Control Register
The output drivers of the SAE 81C90/91’s transmit pins (TXn) can be individually configured. Thus
they can be adapted to the requirements of the external bs system.
n = 0, 1
Note: This register can only be written when bit IM (MOD.0) is set.

Output Mode
’0X’: Normal Mode:
TX0 = Bit Sequence,
TX1 = Bit Sequence.
’10’: Test Mode:
TX0 = Bit Sequence,
TX1 = RX0.
’11’: Clock Mode:
TX0 = Bit Sequence,
TX1 = Bit Clock.
OCPn
Output Polarity
’0’:
Output is driven directly with CAN data.
’1’:
Output is driven with inverted CAN data.
OCTNn
Negative Output Transistor Control
’0’:
The low side output transistor TnN is disabled.
’1’:
The low side output transistor TnN drives the pin according to data.
OCTPn
Positive Output Transistor Control
’0’:
The high side output transistor TnP is disabled.
’1’:
The high side output transistor TnP drives the pin according to data.
