7.8
Memory Timing
Read and write access to the I/O memory takes one CPU clock cycle. A write to SRAM takes one cycle, and a read from
SRAM takes two cycles. EEPROM page load (write) takes one cycle, and three cycles are required for read. For burst
read, new data are available every second cycle. Refer to the instruction summary for more details on instructions and
instruction timing.
7.9
Device ID and Revision
Each device has a three-byte device ID. This ID identifies Atmel as the manufacturer of the device and the device type. A
separate register contains the revision number of the device.
7.10
I/O Memory Protection
Some features in the device are regarded as critical for safety in some applications. Due to this, it is possible to lock the
I/O register related to the clock system, the event system, and the advanced waveform extensions. As long as the lock is
enabled, all related I/O registers are locked and they can not be written from the application software. The lock registers
themselves are protected by the configuration change protection mechanism.
7.11
Flash and EEPROM Page Size
The flash program memory and EEPROM data memory are organized in pages. The pages are word accessible for the
flash and byte accessible for the EEPROM.
Table 7-2 on page 14 shows the Flash Program Memory organization and Program Counter (PC) size. Flash write and
erase operations are performed on one page at a time, while reading the Flash is done one byte at a time. For Flash
access the Z-pointer (Z[m:n]) is used for addressing. The most significant bits in the address (FPAGE) give the page
number and the least significant address bits (FWORD) give the word in the page.
Table 7-2.
Number of words and pages in the flash.
Table 7-3 on page 15 shows EEPROM memory organization. EEEPROM write and erase operations can be performed
one page or one byte at a time, while reading the EEPROM is done one byte at a time. For EEPROM access the NVM
address register (ADDR[m:n]) is used for addressing. The most significant bits in the address (E2PAGE) give the page
number and the least significant address bits (E2BYTE) give the byte in the page.
