■The frame handler’s functions include
▲Status signaling via the STAT register and the SPI status byte
▲Automatic CRC checking of the master message with indication via STAT register and the SPI status byte
▲Automatic CRC generation and replacement in the CKS byte at the end of each device message
▲Maskable interrupt flags for different timeouts, start of transmission, start of receiving, framebuffer level, and completed reception of a master message (see registers INT_EN_FH and INT_SRC_FH)
▲Maskable interrupt flag for automatic wake-up request detection in SIO mode (see registers INT_EN_SIO and INT_SRC_SIO)
