X3102
Read Status Register (RDSTAT)
The Read Status Register (RDSTAT) command returns the
status of the X3102. The Status Register contains three bits
that indicate whether the voltage regulator is stabilized, and
if there are any protection failure conditions. The operation
of the RDSTAT instruction is shown in Figure 24.
Set ID Lock (SET IDL)
The contents of the EEPROM memory array in the X3102
can be locked in one of eight configurations using the SET
ID lock command. When a section of the EEPROM array is
locked, the contents cannot be changed, even when a valid
write operation attempts a write to that area. The SET IDL
command operation is shown in Figure 25.
