Datasheet - Detailed Description
7.3 Device Communication / Programming
Note:   r stands for reserved bits. They must not be modified, unless otherwise noted.
Remark:
1. Send EN PROG (command 16) in normal mode before accessing the OTP in extended mode.
2. OTP assignment will be defined/updated.
Command
5-bit command: cmd<4:0> ?bit<50:46>
Data
34-bit data: data<45:0> ?bit<45:0>
Interface Modes
Normal read operation mode
cmd<4:0> = <00xxx> ?1 DCLK per data bit
Extended read operation mode
cmd<4:0> = <01xxx> ?4 DCLK per data bit
Normal write operation mode
cmd<4:0> = <10xxx> ?1 DCLK per data bit
Extended write operation mode
cmd<4:0> = <11xxx> ?4 DCLK per data bit
