P89LPC9331/9341/9351/9361
8-bit microcontroller with accelerated two-clock 80C51 core
without additional components. Two methods are available to accomplish IAP. A set of
predefined IAP functions are provided in a Boot ROM and can be called through a
common interface, PGM_MTP. Several IAP calls are available for use by an application
program to permit selective erasing and programming of flash sectors, pages, security
bits, configuration bytes, and device ID. These functions are selected by setting up the
microcontroller’s registers before making a call to PGM_MTP at FF03H. The Boot ROM
occupies the program memory space at the top of the address space from FF00H to
FEFFH, thereby not conflicting with the user program memory space.
In addition, IAP operations can be accomplished through the use of four SFRs consisting
of a control/status register, a data register, and two address registers. Additional details
may be found in the P89LPC9331/9341/9351/9361 User manual.
7.30.8 ISP
ISP is performed without removing the microcontroller from the system. The ISP facility
consists of a series of internal hardware resources coupled with internal firmware to
facilitate remote programming of the P89LPC9331/9341/9351/9361 through the serial
port. This firmware is provided by NXP and embedded within each
P89LPC9331/9341/9351/9361 device. The NXP ISP facility has made in-system
programming in an embedded application possible with a minimum of additional expense
in components and circuit board area. The ISP function uses five pins (VDD, VSS, TXD,
RXD, and RST). Only a small connector needs to be available to interface your application
to an external circuit in order to use this feature.
7.30.9 Power-on reset code execution
The P89LPC9331/9341/9351/9361 contains two special flash elements: the Boot Vector
and the Boot Status bit. Following reset, the P89LPC9331/9341/9351/9361 examines the
contents of the Boot Status bit. If the Boot Status bit is set to zero, power-up execution
starts at location 0000H, which is the normal start address of the user’s application code.
When the Boot Status bit is set to a value other than zero, the contents of the Boot Vector
are used as the high byte of the execution address and the low byte is set to 00H.
Table 10 shows the factory default Boot Vector setting for these devices. A
factory-provided bootloader is pre-programmed into the address space indicated and
uses the indicated bootloader entry point to perform ISP functions. This code can be
erased by the user.
Remark: Users who wish to use this loader should take precautions to avoid erasing the
1 kB sector that contains this bootloader. Instead, the page erase function can be used to
erase the first eight 64-byte pages located in this sector.
A custom bootloader can be written with the Boot Vector set to the custom bootloader, if
desired.
