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

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.
