DAC_nCLR

IM_BBANK49

DAC clear

 

 

 

DAC_nLDAC

IM_BBANK50

DAC load signal

 

 

 

DAC_A0

IM_BBANK51

DAC address bit

ADC_CLK

IM_CLK

ADC clock

 

 

 

The ADCs are clocked from a 4MHz oscillator. This also supplies the IM_CLK signal routed to the logic module FPGA. This is used in the example logic to clock the DC-DC converter PrimeCell peripheral and the stepper motor interfaces.
