CS4270
8.3
Mode Control - Address 03h
8.3.1 ADC Functional Mode & Master / Slave Mode (Bits 5:4)
Function:
In Control Port Master Mode, the user must configure the CS4270 Speed Mode with these bits. In Control
Port Slave Mode, the CS4270 auto-detects speed mode.
8.3.2 Ratio Select (Bits 3:1)
Function:
These bits are used to select the clocking ratios.
8.3.3 PopGuard Disable (Bit 0)
Function:
Disables PopGuard when set. PopGuard is enabled by default.
8.4
ADC and DAC Control - Address 04h
8.4.1 ADC HPF Freeze A (Bit 7)
Function:
When this bit is set, the internal high-pass filter for the selected channel will be disabled.The current DC
offset value will be frozen and continuously subtracted from the conversion result.
