Vhold1

19 -

voltage holding pin; this pin is internally connected to the

Vreg(3.3) and Vhold2 pins. When the VCC pin is connected to

+5 V, this pin will output 3.3 V, hence it should not be

connected to +5 V. When the VCC pin is connected to

+3.3 V, this pin can either be connected to +3.3 V or left

unconnected. In all cases this pin should be decoupled to

DGND.

22 I

read strobe input

write strobe input

Vhold2

24 -

voltage holding pin; this pin is internally connected to the

Vreg(3.3) and Vhold1 pins. When the VCC pin is connected to

+5 V, this pin will output 3.3 V, hence it should not be

connected to +5 V. When the VCC pin is connected to

+3.3 V, this pin can either be connected to +3.3 V or left

unconnected. In all cases this pin should be decoupled to

DGND.

DREQ1

25 O

HC’s DMA request output (programmable polarity); signals

to the DMA controller that the ISP1161 wants to start a

DMA transfer; see HcHardwareConfiguration register
