EEPROM Programming Interface
SAB-C513A-H
9.2.4.2
Memory Select Register PMSEL
This register specifies which EEPROM memory cells or memory blocks will be accessed during a
write or delete operation. The smallest amount of memory that can be accessed at a time is one
byte, the largest is the whole memory. For read operations the settings of this register have no
effect.
Programming Interface Register PMSEL (Address 01H)
Reset Value : XXX00000B
Bit
Function
–
Reserved Bits
These bits must be written with ’0’. During reads these bits will be undefined.
SEL4 - 0
Select Mode Bits
These bits allow to define various granularities for writing or deleting specific
memory areas. Single byte, 64 byte or 1KB byte blocks as well as even/odd
addresses in 64 byte/1K byte blocks can be selected according the table
below.
All other combination of SEL4-0 are not defined and might lead to
unpredictable results.

The address in PADRH/PADRL specifies the byte to be
accessed.
0 0 0 0 1
The complete 1KB block which contains the byte addressed
by PADRH/PADRL is selected.
0 0 0 1 0
The complete 64 byte block which contains the byte
addressed by PADRH/PADRL is selected.
0 0 1 0 1
If A0=0 all even addressed bytes, if A0=1 all odd addressed
bytes of the1KB block which contains the byte addressed by
PADRH/PADRL are selected.
0 0 1 1 0
If A0=0 all even addressed bytes, if A0=1 all odd addressed
bytes of the 64 byte block which contains the byte addressed
by PADRH/PADRL are selected.
1 1 0 0 1
With this combination of SEL4-0 the total 12K memory is
selected.This combination is useful for fast erase/fill
operations of the EEPROM memory.
1 1 1 0 1
If A0=0 all even addressed bytes, if A0=1 all odd addressed
bytes of the total 12K memory are selected.
