The following rules apply for the use of input bit commands:
• Only one iVu input bit can be set at a time
• Corresponding ACK bits are set high only on completion of
the command (if the iVu input bit is still high)
• Corresponding ACK bits are cleared when the iVu input bit
is cleared
• When multiple iVu input bits are set simultaneously, the
Execution Error input bit is set and an Error Code value is
reported in the Error Code register
• The Execution Error iVu output bit is cleared when all ACK
bits are cleared, or a new valid command is received
