-
analog ground
A
connect to the external bias resistor; must be connected to
ground via a 12.0 k
±
1 % resistor
I
reset input (500
μ
s); a LOW level produces an asynchronous
reset; connect to V
CC

circuit)
TTL; 5 V tolerant
I
End-of-transfer input (programmable polarity); used in DMA
slave mode only; when not in use, connect this pin to V
CC(I/O)
through a 10 k
resistor
input pad; TTL; 5 V tolerant
O
DMA request (programmable polarity) output; when not in
use, connect this pin to ground through a 10 k
resistor; see
Table 54
and
Table 55
TTL; 4 ns slew-rate control
I
DMA acknowledge input (programmable polarity); when not
in use, connect this pin to V
CC(I/O)
through a 10 k
resistor;
see
Table 54
and
Table 55
TTL; 5 V tolerant
I
DMA read strobe input (programmable polarity); when not in
use, connect this pin to V
CC(I/O)
through a 10 k
resistor; see
Table 54
and
Table 55
TTL; 5 V tolerant
I
DMA write strobe input (programmable polarity); when not in
use, connect this pin to V
CC(I/O)
through a 10 k
resistor; see
