6.11.3 GetOTPParam
This command is provided to the circuit by the master to read the content of the OTP Memory. For
more information refer to Table 9: OTP Memory Structure on page 21.
The master sends either type#7 or type#8 preparing frame:
Note:
After type#7 or type#8 preparing frame the master sends a type#6 reading frame to retrieve the
circuit’s in-frame response:
HW[2:0]: Not stored in OTP memory, the hardwired address is returned by GetOTPParam as if stored
at address 0x02 of the OTP memory.
