Bit 3—Flash Memory Control Register Enable (FLSHE): Setting the FLSHE bit to 1 enables
read/write access to the flash memory control registers. If FLSHE is cleared to 0, the flash
memory control registers are deselected. In this case, the flash memory control register contents
are retained.
Bit 2—Reserved: Do not write 1 to this bit.
Bits 1 and 0—Internal Clock Select 1 and 0 (ICKS1, ICKS0): These bits control 8-bit timer
operation. See section 12, 8-Bit Timers, for details.
21.6
When pins are set to on-board programming mode, program/erase/verify operations can be
performed on the on-chip flash memory. There are two on-board programming modes: boot mode
and user program mode. The pin settings for transition to each of these modes are shown in table
21.6. For a diagram of the transitions to the various flash memory modes, see figure 21.3.
Only advanced mode setting is possible for boot mode.
In the case of user program mode, established in advanced mode or normal mode, depending on
the setting of the MD0 pin. In normal mode, only programming of a 56-kbyte area of flash
memory is possible.
