PICNIC Signals & Names 
======================

This is a list of the main signals needed to run the PICNIC array, and
their names as used in the block diagrams, electronics schematics and
detailed signal lists. This is meant as a summary, to help understand
the rest of the documentation.

Readout Clocks: (0-5V)
**************

Name	Name@DIO32F	Name@DRIVER Board
			Input	Output
-----------------------------------------
PIXEL	DIOA0		A0	PXL			
LINE	DIOA1		A1	LN
LSYNC	DIOA2		A2	LSY
FSYNC	DIOA3		A3	FSY
READ	DIOA6		A6	CLR(*)
RESET	DIOA7		A7	RST

Note:

(*) The NICMOS3 CLEAR clock has been replaced by the READ clock 
in PICNIC. The DRIVER pcb was not modified for implementation
with PICNIC, which is why the CLR label is still used.   

ADC Control Clocks: (0-5V)
