33.3.11 Power-on Reset Characteristics
Table 33-74. Power-on reset characteristics.
Note:
1.
V
POT- values are only valid when BOD is disabled. When BOD is enabled VPOT- = VPOT+.
33.3.12 Flash and EEPROM Memory Characteristics
Table 33-75. Endurance and data retention.
Table 33-76. Programming time.
Notes:
1.
Programming is timed from the 2MHz internal oscillator.
2.
EEPROM is not erased if the EESAVE fuse is programmed.
