These registers provide an indication of events that have occurred since the last
time it was read. These bits are not affected by the programming of the Receive
High-Speed Serial Interrupt Enables register, which only determines whether the
status of the bits in these registers is propagated to the INTB output.
LOSI:
The LOSI bit is set to logic 1 whenever the associated LOSV register bit
changes state. This bit is reset immediately after a read to this register.
LCDI:
The LCDI bit is set to logic 1 whenever the associated LCDV register bit
changes state. This bit is reset immediately after a read to this register.
ACTI:
The ACTI bit is set to logic 1 whenever the associated ACTV register bit
changes state. This bit is reset immediately after a read to this register.
CELLERRI:
The CELLERRI bit is set high when a non-zero remainder occurs for the
CRC-8 protecting the entire cell. This bit is reset immediately after a read to
this register.
HCSI:
The HCSI bit is set high when a HCS error is detected. This bit is reset
immediately after a read to this register.
