Data

Bit7: Read Only

The logical 1 indicates the device is busy due to a Serial Bus transaction or another ISA bus

transaction. By checking this bit, multiple ISA drivers can use the MON35W42 without interfering

with

each other or a Serial Bus driver. It is the user's responsibility not to have a Serial Bus and ISA bus

operations at the same time.

This bit is:

Set: with a write to Port x5h or when a Serial Bus transaction is in progress.

Reset: with a write or read from Port x6h if it is set by a write to Port x5h, or when the Serial Bus

transaction is finished.
