Function
Ready (Intel bus mode)
Data Transfer Acknowledge (Motorola mode)
During a slave access (register read/write) this
signal (output) indicates, that the SEROCCO-H 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.
Reset
With this active low signal the on-chip registers
and state machines are forced to reset state.
During Reset all pins are in a high impedance
state.
