In-System Programming (ISP): In-System Programming is performed without
removing the microcontroller from the system. The In-System Programming facility
consists of a series of internal hardware resources coupled with internal rmware to
facilitate remote programming of the P89LPC924/925 through the serial port. This
rmware is provided by Philips and embedded within each P89LPC924/925 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 ve 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. Please see the
P89LPC924/925 User’s
Manual for additional details.
In-Application Programming (IAP): Several In-Application Programming (IAP) calls
are available for use by an application program to permit selective erasing and
programming of Flash sectors, pages, security bits, conguration bytes, and device
identication. 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 FF03H. Please see the
P89LPC924/925 User’s
Manual for additional details.
In-Circuit Programming (ICP): In-Circuit Programming is a method intended to
allow commercial programmers to program and erase these devices without
removing the microcontroller from the system. The In-Circuit Programming facility
consists of a series of internal hardware resources to facilitate remote programming
of the P89LPC924/925 through a two-wire serial interface. Philips has made in-circuit
programming in an embedded application possible with a minimum of additional
expense in components and circuit board area. The ICP function uses ve pins (VDD,
VSS, P0.5, P0.4, and RST). Only a small connector needs to be available to interface
your application to an external programmer in order to use this feature.
8.26 User conguration bytes
A number of user-congurable features of the P89LPC924/925 must be dened at
power-up and therefore cannot be set by the program after start of execution. These
features are congured through the use of the Flash byte UCFG1. Please see the
P89LPC924/925 User’s Manual for additional details.
8.27 User sector security bytes
There are four or eight User Sector Security Bytes, depending on the device, each
corresponding to one sector. Please see the
P89LPC924/925 User’s Manual for
additional details.
