OTP

The CCP

™

emulator provides OTP programming capabilities. Several operations can be

performed:

Table 4-1. OTP Programming Operations and Functions

Operations Functions Performed

BLANK CHECK checks whether the OTP device is blank.

VERIFY compares the contents of the Z8

Code Memory and the OTP

device.

EXAMINE copies the contents of the OTP device to the Z8 Code Memory.

PROGRAM writes the contents of the Z8 Code Memory to the OTP device.

CHECKSUM calculates the Checksum of the OTP device only and

displays it on the screen.

Notes:

1. To obtain a Data I/O (such as UniSite, 3900, or 2900) calculated Checksum, the user

should first download the file with 00 padding option, then perform the OTP program-

ming. This is because Data I/O fills its memory with 00 after power up.

2. Checksum differences may occur. During user-program download, the memory is

padded with code outside the user program memory if the user program is less than

the emulation memory. The memory is padded with either 00, FF, or nothing according

to user selection. This will not effect the user program; however, it will effect the

calculation of the Checksum during the OTP programming because the Checksum is

calculated through out the whole memory size of the OTP.
