22.3.2.3 Reading SCDATA Registers

There are also two suggested methods for reading an SCD register:
  • The register can be read directly within the host code from SCDATA, or
  • The BiSS interrupt can be configured to trigger at the end of every BiSS transmission
To configure the BiSS interrupt, set the interrupt enable, clear the interrupt flag and confirm there is an interrupt service routine (ISR). In both methods, it is recommended to poll for an end of transmission (_EOT) to verify a successful transmission. If CRC is being used, it is also recommended to poll after the Client SCD valid bit (_CLSCDVx) is set. This bit is set after a successful CRC value is detected. Once these are polled and successfully checked, the B1SCDATA0L and B1SCDATA0H can be read by the user.
