9.2.4.3
Data Register PDATA
This register contains the data to be written into the selected memory bytes during write operations.
When reading from this address, the contents of the memory byte selected by PADRH/PADRL will
be put onto the data bus. The written content of PDATA will not be disturbed by reading PDATA.
Programming Interface Register PDATA (Address 02H)
Reset Value : XXH
9.2.4.4
Address Low Register PADRL and PADRH
The PADRH/PADRL registers contain the 14-bit address of the EEPROM byte to be accessed
during read or write operations. The LSB part of the address is stored in PADRL and the MSB part
of the address is stored in PADRH. PADRL is combined with PADRH to form the complete 14-bit
address.
Depending on the settings in the register PMSEL (SEL4-0 bits) the combined address also may
specify memory blocks for write/erase operations. If automatic address increment is selected the
combined address will be incremented by 1 after every read access.
Reading the PARDH/PADRL registers will put its actual value onto the data bus. Bits 6 and 7 of
PADRH must be written with ’0’. During reads these bits will be undefined.
