Signature Section
Calibration Section
Latching of Configuration Bits
Configuration bits are not affected by a chip erase but they can be cleared using the configura-
tion section erase command (see
configuration bits are locked if Non-Volatile Lock Bit 1 (NVLB1) is programmed.
All configuration bits are latched either when the device is reset or when the device exits the
external programming mode. Changes to configuration bit values have no effect until the device
leaves the external programming mode.
The signature section is a dedicated memory area used for storing miscellaneous device infor-
mation, such as the device signature. Most of this memory section is reserved for internal use,
as shown in
Table 15-7.
ATtiny4/5/9/10 have a three-byte signature code, which can be used to identify the device. The
three bytes reside in the signature section, as shown in
ATtiny4/5/9/10 is given in
Table 15-8.
ATtiny4/5/9/10 have one calibration byte. The calibration byte contains the calibration data for
the internal oscillator and resides in the calibration section, as shown in
reset, the calibration byte is automatically written into the OSCCAL register to ensure correct fre-
quency of the calibrated internal oscillator.
