Write/nRead
W/nR
I
Input. Defines the direction of synchronous
cycles. Write cycles when high, read cycles
when low.
181
nVL Bus
Access
nVLBUS
IP
Input.
synchronous bus interface is configured for VL
Bus accesses. Otherwise the SMC91C100 is
configured for EISA DMA burst accesses.
Does not affect the asynchronous bus
interface.
When
low
the
SMC91C100
105
Local Bus
Clock
LCLK
I
Input. Used to interface synchronous buses.
Maximum frequency is 50 MHz. Limited to 8.33
MHz for EISA DMA burst mode.
175
Asynchron-
ous Ready
ARDY
OD16
Open drain output. ARDY may be used when
interfacing asynchronous buses to extend
accesses. Its rising (access completion) edge
is controlled by the XTAL1 clock and therefore
asynchronous to the host CPU or bus clock.
106
nSynchron-
ous Ready
nSRDY
O16
Output. This output is used when interfacing
synchronous buses and nVLBUS=0 to extend
accesses. This signal remains normally
inactive, and its falling edge indicates
completion. This signal is synchronous to the
bus clock LCLK.
109
nReady
Return
nRDYRTN
I
Input. This input is used to complete
synchronous read cycles. In EISA burst mode
it is sampled on falling LCLK edges, and
synchronous cycles are delayed until it is
sampled high.
176
Interrupt
INT0-INT3
O24
Outputs. Only one of these interrupts is
selected to be used; the other three are tri-
stated. The selection is determined by the value
of INT SEL1-0 bits in the Configuration
Register.
