Interrupt Vector Allocation
The W523Sxx provides a total of 4 trigger inputs to communicate with the outside world. Each trigger
pin can invoke 2 dedicate interrupt vectors depending on TG pins’ status (rising or falling). The table
below shows the relationship between triggers’ status and interrupt vectors.

CPU Interface
The W523Sxx can communicate with an external microprocessor through a simple serial CPU
interface. The CPU interface consists of TG1, TG2 and STPA/BUSY pins, which are shown below:

3. The "Clock" frequency of the TG2 pin can be set in the range: 10 KHz - 1 MHz.
Busy signal will output "high" after the end of transmission. The rising timing of Busy signal is
