12.3.2 Unlock Device
Table 36:
Table 37:
This command unlocks the ISP1181A 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
(8-bit bus: lower byte first). The bit allocation of the Lock Register is given in
Code (Hex): B0 — unlock the device
Transaction — write 2 bytes (unlock code)

Description
no error
PID encoding error; bits 7 to 4 are not the inverse of bits 3 to 0
PID unknown; encoding is valid, but PID does not exist
unexpected packet; packet is not of the expected type (token, data, or
acknowledge), or is a SETUP 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
sync error
wrong (unexpected) toggle bit in DATA PID; data was ignored
