Description
Communications (ISOlink) error.
1 = Indicates a communication problem between the PCT303D and the
PCT303W. When it goes high, it remains high until a logic 0 is written to it.
Frame detect. Read-only.
1 = Indicates ISOLink frame lock has been established.
0 = Indicates ISOLink has not established frame lock.
Reserved. Read returns zero.
Loop current sense. Read-only.
Four-bit value returning the loop current in 6mA increments. 0 = Loop current <
6mA. 1111 = Loop current > 120mA. See “Loop Current Monitor” on page 25.
