Figure 39. Write Volatile Configuration Register instruction sequence
Read Volatile Enhanced Configuration Register
The Read Volatile Enhanced Configuration Register (RDVECR) instruction allows the
Volatile Configuration Register to be read.
Figure 40. Read Volatile Enhanced Configuration Register instruction sequence
Write Volatile Enhanced Configuration Register
The Write Volatile Enhanced Configuration register (WRVECR) instruction allows new
values to be written to the Volatile Enhanced Configuration register. Before it can be
accepted, a write enable (WREN) instruction must previously have been executed. After the
write enable (WREN) instruction has been decoded and executed, the device sets the write
enable latch (WEL). In case of Fast POR, the WREN instruction is not required because a
WREN instruction gets the device out from the Fast POR state (see
POR).
