Detailed Description

Configuration for the AFE configuration register group A (CFGRA).

Configuration Register Group B packet for each device.

Configuration Register Group A packet for each device.

STMCOMM + clock cycles.

WRCOMM + mux pin.

COMM Register Config, refer to pg 64 table 49.

Configuration for the AFE configuration register group B (CFGRB).

The configuration includes:

• ADC Mode Option Bit (adcopt): Determines ADC conversion modes
• Discharge Timer Enable (dten): Enable/disable discharge timer
• References Powered Up (refon): Keeps references powered up until watchdog timeout
• GPIO Pin Pull-Down Config (gpio): Configures GPIO pull-downs
• Undervoltage Threshold (undervoltage): Sets undervoltage threshold
• Overvoltage Threshold (overvoltage): Sets overvoltage threshold
• Discharge Cell Bitset (discharge_bitset): Enables/disables discharge for specific cells
• Discharge Timeout (discharge_timeout): Sets discharge timeout duration

  Note

  See Table 54 on Page 65 for the exact layout.

  The configuration includes:
• GPIO Pin Pull-Down Config (gpio): Configures GPIO pull-downs
• Discharge Cell Bitset (discharge_bitset): Enables/disables discharge for specific cells
• Discharge Timeout (discharge_timeout): Sets discharge timeout duration
• Digital redundancy path selection (path_select): Selects which ADC has redundancy applied
• Enable discharge timer monitor (discharge_timer_monitor): Enable/disable discharge timer monitor function
• Force Digital redundancy failure (force_fail): Force digital redundancy comparison for ADC conv to fail (if 1) else normal
• Mute status (mute): 1: Mute is activated discharging is disabled, 0: mute is deactivated
• Reserved bits (reservedx): Placeholder (doesn't really do anything)

  Note

  See Table 55 on Page 65 for the exact layout.

  The following outline the config settings variables:
• Initial communication control bits (ICOMx): For SPI. Determine CSB signal behaviour (Write code). Value is 0111 (Read code)
• Communication Data byte (Dx): Data transmitted transmitted or received from slave
• Final Communication Control Bits (FCOMx): Specific signals for master/slave acknowledgments and stop conditions.

  Note

  For detailed notes check out Table 20 (p40), Table 21 (p40), Table 52 (p66)
