Then device is driving the data on Port 2.
It is possible to alternate programming and verification operation (see Paragraph
Programming Algorithm). Please make sure the voltage on the EA# pin has actually
been lowered to VDD before performing the verifying operation.
PSEN# and the other control signals have to be released to complete a sequence of
verifying operations or a sequence of programming and verifying operations.

Notes: 1. To preserve the secrecy of on-chip code memory when encrypted, the Encryption
Array can not be verified.
