Read Status Register (RDSTAT)
The Read Status Register (RDSTAT) command
returns the status of the X3100 or X3101. The Status
Register contains three bits that indicate whether the
voltage regulator is stabilized, and if there are any pro-
tection failure conditions. The operation of the
RDSTAT instruction is shown in Figure 16.
Set ID Lock (SET IDL)
The contents of the EEPROM memory array in the
X3100 or X3101 can be locked in one of eight configu-
rations using the SET ID lock command. When a sec-
tion 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 17.
