Pseudo Code Example

The following shows a pseudo code sequence to program the initial register values to the NVM of the DAC53701. The values given here are for the design choices made in the Design Notes.

Pseudo Code Example for GPI to PWM

//SYNTAX: WRITE <REGISTER NAME (Hex code)>, <MSB DATA>, <LSB DATA>  
//Power-up the device, internal reference disabled, set code step and slew rate
WRITE GENERAL_CONFIG(0xD1), 0x0A, 0x20 
//Configure GPI for Margin-High, Low function
WRITE CONFIG2(0xD2), 0x08, 0x00 
//Write DAC margin high code
WRITE DAC_MARGIN_HIGH(0x25), 0x0C, 0xCC
//Write DAC margin low code
WRITE DAC_MARGIN_LOW(0x26), 0x03, 0x34
//Enable the GPI, start CWG, save settings to NVM
WRITE TRIGGER(0xD3), 0x05, 0x10
