the Boot Vector and Boot Status Bit. After programming the Flash, the status byte
should be programmed to zero in order to allow execution of the user’s application
code beginning at address 0000H.
In-System Programming (ISP):
removing the microcontroller from the system. The In-System Programming facility
consists of a series of internal hardware resources coupled with internal firmware to
facilitate remote programming of the P89LPC930/931 through the serial port. This
firmware is provided by Philips and embedded within each P89LPC930/931 device.
The Philips In-System Programming 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 (V
RST). Only a small connector needs to be available to interface your application to an
external circuit in order to use this feature.
In-Application Programming (IAP):
are available for use by an application program to permit selective erasing, reading,
and programming of Flash sectors, pages, security bits, configuration bytes, and
device id. All calls are made through a common interface, PGM_MTP. The
programming functions are selected by setting up the microcontroller’s registers
before making a call to PGM_MTP at FF00H.
A number of user-configurable features of the P89LPC930/931 must be defined at
power-up and therefore cannot be set by the program after start of execution. These
features are configured through the use of the Flash byte UCFG1. Please see the
P89LPC930/931 User’s Manual for additional details.
There are eight User Sector Security Bytes, each corresponding to one sector.
Please see the P89LPC930/931 User’s Manual for additional details.
