Table 98.
This command unlocks the ISP1161A1’s DC from write-protection mode after a ‘resume’.
In ‘suspend’ state all registers and FIFOs are write-protected to prevent data corruption by
external devices during a ‘resume’. Also, the register access for reading is possible only
after the ‘Unlock Device’ command is executed.
After waking up from ‘suspend’ state, the firmware must unlock the registers and FIFOs
via this command, by writing the unlock code (AA37H) into the Lock register. The bit
allocation of the Lock register is given in
Code (Hex): B0 — unlock the device
Transaction — write 1 word (unlock code)

Description
no error
PID encoding error; bits 7 to 4 are not the inverse of bits 3 to 0

acknowledge), or is a token to a non-control endpoint
token CRC error
data CRC error
time-out error
babble error
unexpected end-of-packet
sent or received NAK (Not AcKnowledge)
sent Stall; a token was received, but the endpoint was stalled
overflow; the received packet was larger than the available buffer space
sent empty packet (ISO only)
bit stuffing error
