7.4.1 Normal Mode 1 (NOM1)
On Power-on-reset of the device, AS8510 goes into STOP State.
Transition to Normal mode1 (NOM1) occurs when the “START BIT” D0 of Mode Control Register MOD_CTL_REG in
Table 33
is set to “1”
through the serial port SPI. Data Rate of voltage and current channels can be independently programmed and both the channels generate
interrupts for every output available from ADC. The interrupt signal is generated on the INT pin. The width of the interrupt pulse is eight cycles of
lp_clk. The data is stable up to the next interrupt. If the data rate is different for the two channels, the interrupt rate would follow the higher rate
among the two channels. Data update can be known by reading the status register. The functionality is explained in the waveform shown in
Figure
5. When the device is configured to NOM1 Mode from any mode the configuration should be through the STOP state only.
