5.4 EEPROM
PSoC EEPROM memory is a byte-addressable nonvolatile memory. The CY8C36 has up to 2 KB of EEPROM memory to store user
data. Reads from EEPROM are random access at the byte level. Reads are done directly; writes are done by sending write commands
to an EEPROM programming interface. CPU code execution can continue from flash during EEPROM writes. EEPROM is erasable
and writeable at the row level. The EEPROM is divided into 128 rows of 16 bytes each.
The CPU can not execute out of EEPROM. There is no ECC hardware associated with EEPROM. If ECC is required it must be handled
in firmware.
5.5 Nonvolatile Latches (NVLs)
PSoC has a 4-byte array of nonvolatile latches (NVLs) that are used to configure the device at reset. The NVL register map is shown
in
Table 5-2. Device Configuration NVL Register Map
The details for individual fields and their factory default settings are shown in
Table 5-3. Fields and Factory Default Settings
Although PSoC Creator provides support for modifying the device configuration NVLs, the number of NVL erase / write cycles is limited
