The OTP DATA READ (AFh-30h) command is used to read data from a page within the
OTP area. An OTP page within the OTP area is available for reading data whether or not
the area is protected.
To use the OTP DATA READ command, issue the AFh command. Then issue five
ADDRESS cycles: the first two ADDRESS cycles are the column address, and for the
remaining three cycles select a page in the range of 02h-00h-00h through 0Bh-00h-00h.
Finally, issue the 30h command.
R/B# goes LOW (
READ STATUS (70h) command and the RESET (FFh) command are the only commands
valid during the OTP DATA READ operation. Bit 5 of the status register will reflect the
state of R/B#. For details, refer to Table 11 on page 28.
Normal READ operation timings apply to OTP read accesses (see Figure 30). Additional
pages within the OTP area can be selected by repeating the OTP DATA READ command.
