Shared with
Window
Programming
commands
N/A
Other than commands listed above, all other bit patterns may result in undefined behavior.
The OTP commands listed above should only be used with OTP version of UC1682.
Command 39~42 are shared with command 32~35, and they have exactly the same code. The
interpretation of these four commands depends on register OTPC[3]. When OTPC[3]=0, they are
interpreted as
Window Programming
commands. When OTPC[3]=1, they are
OTP Control
commands.
OTPM and PM are actually the same register. The usage of this register is determined by OTPC[3] in
similar ways as Command 39~42.
After OTP-ERASE or OTP-PROGRAM operation (Set OTPC[3]=1) , always
a) remove TST4 power source;
b) Do a full Vdd ON-OFF cycle; before resuming normal operation.
