digital ground

VHOLD1

19 -

voltage holding pin 1; internally connected to the VREG(3V3)

and VHOLD2 pins. When VCC is connected to 5 V, this pin

will output 3.3 V, hence do not connect it to 5 V. When VCC

is connected to 3.3 V, this pin can either be connected to

3.3 V or left unconnected. In all cases, decouple this pin to

DGND.

no connection; leave this pin open

CS_N

21 I

chip select input

RD_N

22 I

read strobe input

WR_N

23 I

write strobe input

VHOLD2

24 -

voltage holding pin 2; internally connected to the VREG(3V3)

and VHOLD1 pins. When VCC is connected to 5 V, this pin

will output 3.3 V, hence do not connect it to 5 V. When VCC

is connected to 3.3 V, this pin can either be connected to

3.3 V or left unconnected. In all cases, decouple this pin to

DGND.

DREQ

25 O

HC DMA request output (programmable polarity); signals

to the DMA controller that the ISP1160 wants to start a

DMA transfer; see Section 10.4.1

n.c.
