Status Data Byte 2
Notes:
Status Data Byte 2 (bits 2 and 1) lists the possible values of bits 2 and 1 and what the
MC can assume from the bits:
Status Data Byte 2 (Bits 2 and 1)
The MC reads should consider the time it takes for the LAN device driver to deal with
the interrupt (in s). Note that excessive reads by the MC can give false indications.
1. The LAN device driver alive indication is set if one of the LAN device drivers is alive.
2. The LAN interrupt is considered asserted if one of the interrupt lines is asserted.
3. The ICR is considered read if one of the ICRs was read (LAN 0 or LAN 1).

0b = LAN driver is not alive.
1b = LAN driver is alive.
1b = LAN interrupt line is asserted.
0b = LAN interrupt line is not asserted.
1b = ICR register was read since the last read status cycle.
0b = ICR register was not read since the last read status cycle.
Reading the ICR indicates that the driver has dealt with the
interrupt that was asserted.
Reserved
Interrupt is not pending (OK).
New interrupt is asserted (OK).
New interrupt is asserted (OK).
Interrupt is waiting for reading (OK).
Interrupt is waiting for reading by the driver for more than
one read cycle (not OK).
Possible drive hang state.
Previous interrupt was read and current interrupt is pending
(OK).
Interrupt is not pending (OK).
