Configuration Register 00h (Read/Write) BIT # D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 BIT RST — BRNG PG1 PG0 BADC4 BADC3 BADC2 BADC1 SADC4 SADC3 SADC2 SADC1 MODE3 MODE2 MODE1 NAME POR 0 0 1 1 1 0 0 1 1 0 0 1 1 1 1 1 VALUE Bit Descriptions RST: Reset Bit Bit 15 Setting this bit to '1' generates a system reset that is the same as power-on reset. Resets all registers to default values; this bit self-clears. BRNG: Bus Voltage Range Bit 13 0 = 16-V FSR 1 = 32-V FSR (default value) PG: PGA (Shunt Voltage Only) Bits 11, 12 Sets PGA gain and range. Note that the PGA defaults to ÷8 (320-mV range). Table 5 shows the gain and range for the various product gain settings. Table 5. PG Bit Settings(1) PG1 PG0 GAIN RANGE 0 0 1 ±40 mV 0 1 ÷2 ±80 mV 1 0 ÷4 ±160 mV 1 1 ÷8 ±320 mV (1) Shaded values are default. BADC: BADC Bus ADC Resolution/Averaging Bits 7–10 These bits adjust the Bus ADC resolution (9-, 10-, 11-, or 12-bit) or set the number of samples used when averaging results for the Bus Voltage Register (02h).
