7.1.3 PGA & ADC Enabling
Depending on the application objectives, the user may enable or bypass each PGA stage. This is done according to the
word Enable and the coding given in Table 7. To reduce power dissipation, the ADC can also be inactivated while idle.
7.2 ZoomingADC Registers
The system has a bank of eight 8-bit registers: six registers are used to configure the acquisition chain (RegAcCfg0 to
RegAcCfg5), and two registers are used to store the output code of the analog-to-digital conversion (RegAcOutMsb &
Lsb).
(r = read; w = write; rw = read & write)
(1)
Out: (r) digital output code of the analog-to-digital converter. (MSB = Out[15])
(2)
Start: (w) setting this bit triggers a single conversion (after the current one is finished). This bit always reads back 0.
