! 46: * To make handling these commands easier, I added some extra data
! 47: * which is decided by the axe_cmd() routine. Commands are encoded
! 48: * in 16 bites, with the format: LDCC. L and D are both nibbles in
! 49: * the high byte. L represents the data length (0 to 15) and D
! 50: * represents the direction (0 for vendor read, 1 for vendor write).
! 51: * CC is the command byte, as specified in the manual.
