Interrupt Request
This line indicates general interrupt
requests of the layer one functions or the
mailbox. The interrupt sources can be
masked via registers.
In local bus master mode the TE3-CHATT
can monitor external interrupts indicated
via LINT.
Chip Select 2, 1
These signals select external peripherals
when TE3-CHATT is the local bus master.
As long as the local bus master
functionality is disabled these outputs are
set to tri-state.
Byte High Enable (Intel Bus Mode)
In local bus master mode this signal
indicates a data transfer on the upper byte
of the data bus LD(15:8).
This signal has no function in slave mode.
When local bus master functionality is
disabled this output is tri-state.
Byte Access (Motorola Bus Mode)
In local bus master mode this signal
indicates byte transfers.
This signal has no function when the TE3-
CHATT is local bus slave. When local bus
master functionality is disabled this output
is tri-state.
