Figure 10-50. READ_ID Waveform
WRITE_EN (ACh)
The WRITE_EN command enables the TAG memory for programming. If the WRITE_EN command has not been
shifted into the device first, the PROGRAM_TAG, ERASE_TAG and STATUS commands do not take effect. This is
to prevent the TAG memory from erroneous erase or program.
The command is executed when the Chip Select pin is driven from low to high after the 24th dummy clock. Any
extra dummy clocks, if presented before driving the Chip Select pin to high, are ignored. After the Chip Select pin is
driven from low to high, a minimum of three clocks are required to complete the execution of the command.
The effect of this command is terminated by the WRITE_DIS command.
Figure 10-51. WRITE_EN Waveform
WRITE_DIS (78h)
The WRITE_DIS command disables the TAG memory for programming. It does not nullify the READ_TAG and
READ_ID commands.
The command is executed when the Chip Select pin is driven from low to high after the 24th dummy clock. Any
extra dummy clocks, if presented before driving the Chip Select pin to high, are ignored. After the Chip Select pin is
driven from low to high, a minimum of three clocks are required to complete the execution of the command.
