Note:
Register description
EEPROM control/status register (EECSR)
Reset value: 0000 0000 (00h)
Bits 7:2 = Reserved, forced by hardware to 0.
Bit 1 = E2LAT Latch Access Transfer
Bit 0 = E2PGM Programming control and status
If the E2PGM bit is cleared during the programming cycle, the memory data is not
guaranteed
Table 5.
Address
(Hex.)
0020h
This bit is set by software. It is cleared by hardware at the end of the programming
cycle. It can only be cleared by software if the E2PGM bit is cleared.
0: Read mode
1: Write mode
This bit is set by software to begin the programming cycle. At the end of the
programming cycle, this bit is cleared by hardware.
0: Programming finished or not yet started
1: Programming cycle is in progress
