5. Functional Description

5.1. Program Memory – OTP

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

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

address for FPP0 is 0x000. The interrupt entry is 0x010 if used. The OTP program memory for PMS164 is a

1.75KW that is partitioned as Table 1. The OTP memory from address 0x700 to 0x7FF is for system using,

address space from 0x001 to 0x00F and from 0x011 to 0x6FF is user program space.

5.2. Boot Up

POR (Power-On-Reset) is used to reset PMS164 when power up. The boot up time is 3000 ILRC clock cycles.

Customer must ensure the stability of supply voltage after power up no matter which option is chosen, the

power up sequence is shown in the Fig. 2 and tSBP is the boot up time.

Please noted, during Power-On-Reset, the VDD must go higher than VPOR to boot-up the MCU.
