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
Table 98
.
Code (Hex): B0 —
unlock the device
Transaction —
write 1 word (unlock code)
14.3.3
Write/Read Scratch Register
This command accesses the 16-bit Scratch Register, which can be used by the
firmware to save and restore information, e.g., the device status before powering
down in ‘suspend’ state. The register bit allocation is given in
Table 100
.
Code (Hex): B2/B3 —
write/read Scratch Register
Transaction —
write/read 1 word
