Parallel Programming Parameters, Pin Mapping, and Commands
All Atmel microcontrollers have a three-byte signature code which identifies the device. This
code can be read in both serial and parallel mode, also when the device is locked. The three
bytes reside in a separate address space. For the ATmega16M1/32M1/64M1 the signature
bytes are given in
Table 27-8.
The ATmega16M1/32M1/64M1 has a byte calibration value for the internal RC Oscillator. This
byte resides in the high byte of address 0x000 in the signature address space. During reset, this
byte is automatically written into the OSCCAL Register to ensure correct frequency of the cali-
brated RC Oscillator.

Table 27-10. No. of Words in a Page and No. of Pages in the EEPROM
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega16M1/32M1/64M1. Pulses are
assumed to be at least 250ns unless otherwise noted.
