5-2. Program Memory - OTP

5-2-1. Program Memory Assignment

The OTP (One Time Programmable) program memory is used to store the program instructions to be

executed. All program codes for each FPP unit are stored in this OTP memory for both FPP0 and FPP1. The

OTP program memory may contains the data, tables and interrupt entry. After reset, the initial address for

FPP0 is ‘h0 and ‘h1 for FPP1. The interrupt entry is ‘h10 if used and interrupt function is for FPP0 only, the

last eight addresses are reserved for system using, like checksum, serial number, etc. The OTP program

memory for PMC232/PMS232 is a 2kx16 bit that is partitioned as Table 1. The OTP memory from address

‘h7F8 to ‘h7FF is for system using, address space from ‘h002 to ‘h00F and from ‘h011 to ‘h7F7 are user

program space. The address ‘h001 is the FPP1 initial address for two FPP units mode and user program for

single FPP unit mode.
