It is initialized by a reset and in hardware standby mode. It is not initialized in software standby
mode.
Bits 2 to 0—RAM2 to RAM0*: These bits are used with bit 3 to reassign an area to RAM (see
table 19.6). They are initialized by a reset and in hardware standby mode. They are not initialized
in software standby mode.
Note: * These bits can be written to in modes 5, 6, and 7 (on-chip flash memory enabled). In other

When an on-board programming mode is selected, the on-chip flash memory can be programmed,
erased, and verified. There are two on-board programming modes: boot mode, and user program
mode. These modes are selected by inputs at the mode pins (MD
indicates how to select the on-board programming modes. For information about turning V
and off, see note (4) in section 19.8, Flash Memory Programming and Erasing Precautions (Dual-
Power Supply).
