AuxDacData

Title:

Auxiliary DAC Data registers

Address:

(Eight registers) $0x18 to $0x1F

Function:

Description:

There are two input registers for each of the four auxiliary DACs. Writing to the AuxDac#LsbData

Writing to the AuxDac#MsbData

appropriate DAC input (only if the RamDacActive bit is set Low for DAC 1).

If the

AuxDac#MsbData register is written while the AuxDac#LsbData register is left constant, the

converter may be treated as an 8-bit DAC.

Writing to this address writes the least significant two bits

of the DacData1 register. These two bits may be read for

test purposes.

Address $0x19

AuxDac1MsbData

Data RW

Writing to this address writes the most significant eight

bits of the DacData1 register and updates DAC 1. This

Address $0x1A

AuxDac2LsbData

Data RW

Writing to this address writes the least significant two bits

of the DacData2 register. These two bits may be read for

test purposes.

Address $0x1B

7:0

AuxDac2MsbData

Data RW

Writing to this address writes the most significant eight

bits of the DacData2 register and updates DAC 2. This

Address $0x1C

7:2

Reserved. These bits should be set Low. Undefined on

read.

AuxDac3LsbData

Data RW

Writing to this address writes the least significant two bits

of the DacData3 register. These two bits may be read for

test purposes.

Address $0x1D

7:0

AuxDac3MsbData

Data RW

Writing to this address writes the most significant eight

bits of the DacData3 register and updates DAC 3. This

Address $0x1E

7:2

Reserved. These bits should be set Low. Undefined on

read.
