7.1 Operating Modes
When the supply voltage is below the threshold VPOR, the AS8002 is in Reset mode. Once the supply voltage is higher than VPOR, the AS8002
goes into Off mode during its initialization time tINIT. In this mode, the current consumption is reduced and only the Control register can be read
or written. Once the register bit chip_en has been set to 1, the chip goes into On mode and can be normally used after tWAKEUP. The chip can
go immediately back to Off mode by setting chip_en to 0.
7.2 SPI Interface
The 16-bit SPI interface enables read / write access to the register blocks and is compatible to a standard micro controller interface, using SPI
Mode 3 (SCLK initial state = high, data latched with rising edge of SCLK).
The SPI module is active as soon as pin SCSB is pulled low. The AS8002 is then ready to read the 8-bit SPI address on the SDI input with every
rising edge of SCLK and writes on its SDO output with the falling edge of SCLK. After 16 clock cycles SCSB has to be set back to high status in
order to reset the interface for the next read/write cycle.
The address is split into an upper 7 bit address (addr[0…6]) and a lower 8
th bit (R/W) containing the read/write information.
Writing data to the AS8002 is established by setting the R/W bit to 0. The 8 bits following this bit on SDI contain the data to be written into the
address specified in the first 8 bits.
Reading data is established by setting the R/W bit to 1. The 8 bits following this bit on SDO contain the data from the address specified in the first
8 bits on SDI.
