Module: Program Memory Writes
When both CP bits (CP1 or CP0) are clear, program
memory writes are disabled. Table 1 shows how the
data sheet specifies writes to the protected FLASH
memory (CP1:CP0 = 00).
Devices marked “ES” (Engineering Sample) have
program memory writes disabled for the configura-
tion shown in the

Note:
The data sheet specification for CP operation (when
CP1:CP0 = 00) was enhanced after manufaturing
began on the “ES” (Engineering Sample) revision of
the device. Future devices will operate to the Data
Sheet specification (DS30221A).

When the manufacture date of a newer ver-
sion of silicon is in production, the last date
where this issue may occur will be specified
in the errata sheet.
