Function
Write Strobe (Intel bus mode only)
This signal indicates a write operation. The
current bus master presents valid data on lines
D(7:0) / D(15:0) during an active WR signal.
In Motorola bus mode, a pull-up resistor to V
recommended on this pin.
Width Of Bus Interface
A low signal on this input selects the 8-bit bus
interface mode.
A high signal on this input selects the 16-bit bus
interface mode. In this case word transfer to/from
the internal registers is enabled. Byte transfers
are implemented by using BLE and BHE (Intel bus
mode) or LDS and UDS (Motorola bus mode)
Clock
The system clock for SEROCCO-M is provided
through this pin.
Interrupt Request
The INT/INT goes active when one or more of the
bits in registers
to these registers clears the interrupt. The INT/
INT line is inactive when all interrupt status bits
are reset.
Interrupt sources can be unmasked in registers
IMR0..IMR2
’0’.
Ready (Intel bus mode)
Data Transfer Acknowledge (Motorola mode)
During a slave access (register read/write) this
signal (output) indicates, that the SEROCCO-M is
ready for data transfer. The signal remains active
until the data strobe (DS in Motorola bus mode,
RD/WR in Intel bus mode) and/or the chip select
(CS) go inactive.
This line is tri-state when unused.
A pull-up resistor to V
function is not used.
