DATA EEPROM (Cont’d)
5.7 REGISTER DESCRIPTION
EEPROM CONTROL/STATUS REGISTER (EEC-
SR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:2 = Reserved, forced by hardware to 0.
Bit 1 = E2LAT Latch Access Transfer
This bit is set by software. It is cleared by hard-
ware 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
Bit 0 = E2PGM Programming control and status
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
Note: if the E2PGM bit is cleared during the pro-
gramming cycle, the memory data is not guaran-
teed
