20. OTP PROGRAMMING

The HMS87C130XA is one-time PROM(OTP) microcon-

troller with 4K/2K bytes electrically programmable read

only memory.

To programming the OTP device, user must use the uni-

versal programmer which is support Hynix microcontrol-

lers.

20.1 DEVICE CONFIGURATION AREA

The Device Configuration Area can be programmed or left

unprogrammed to select device configuration such as secu-

rity bit, power on reset, RC-oscillation, PFD level select

and open drain port selection .

This area is not accessible during normal execution but is

readable and writable during program / verify.
