Clone NXP P89LPC901 Microcontroller Embedded Firmware

Clone NXP P89LPC901 Microcontroller Embedded Firmware also include the content from flash, The P89LPC901 program memory consists of a 16/32/64 kB block.

An In-System Programming (ISP) capability, in a second 8 kB block, is provided to allow the user code to be programmed in-circuit through the serial port. There are three methods of erasing or programming of the Flash memory that may be used.

First, the Flash may be programmed or erased in the end-user application by calling low-level routines through a common entry point (IAP).

Second, the on-chip ISP boot loader may be invoked. This ISP boot loader will, in turn, call low-level routines through the same common entry point that can be used by the end-user application.

Third, the Flash may be programmed or erased using the parallel method by using a commercially available EPROM programmer which supports this device.

When the microcontroller programs its own Flash memory, all of the low level details are handled by code that is contained in Block 1. A user program calls the common entry point in the Block 1 with appropriate parameters to accomplish the desired operation. Boot block operations include erase user code, program user code, program security bits only in the process of Dump NXP P87C575 Microcontroller Embedded Heximal.

A Chip-Erase operation can be performed using a commercially available parallel programer. This operation will erase the contents of this Boot Block and it will be necessary for the user to reprogram this Boot Block (Block 1) with the Philips-provided ISP/IAP code in order to use the ISP or IAP capabilities of this device.
