Detailed Description

Configuration for the AFE configuration register group (CFGR).

WRCFG + all slave registers.

Configuration Register Group (CFGR) packet for EACH device.

STMCOMM + clock cycles.

WRCOMM + mux pin.

COMM Register Config, refer to pg 64 table 49.

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 40 on Page 62 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)

  Devices are ordered with the last slave first
