19.22.3 Flash Memory Operating Modes
Mode Transitions: When the mode pins and the FWE pin are set in the reset state and a reset-
start is executed, the chip enters one of the operating modes shown in figure 19.60. In user mode,
flash memory can be read but not programmed or erased.
Flash memory can be programmed and erased in boot mode, user program mode, and PROM
mode.
Notes: Only make a transition between user mode and user program mode when the CPU is

SWE = 1
