Base + 7		Write		D/A Channel and Control Register

Bit No.		7	6		5	4	3	2	1	0

Name							DAUPDT	DACH2	DACH1	DACH0

DAUPDT		Writing a 1 to this bit updates the D/A chip. All channels with new data written to
		them since the previous update are updated simultaneously. When a 1 is written
		to this bit the other bits in the register are ignored.

When DAUPDT = 0, the remaining bits in this register behave as described below: DACH2-0 D/A channel number, valid range 0-7

Base + 7	Read	Optocoupler Input Port and Edge Detection Register

Bit No.	7	6	5	4	3	2	1	0

Name	OEDGE3	OEDGE2	OEDGE1	OEDGE0	OPTO3	OPTO2	OPTO1	OPTO0

OEDGE3-0 Indicates whether an edge has occurred on the indicated digital input line. 1 edge has occurred since last flip flop reset

0 edge has not occurred since last flip flop reset

These bits are reset when this register is read or when the digital input interrupt flip flop is reset by writing to the CLRO bit in register 8.

OPTO3-0 These signals correspond to the logic state of the optocoupler inputs on J4.
