9.26.4
Flash programming and erasing
Different methods of erasing or programming of the Flash are available. The Flash
may be programmed or erased in the end-user application (IAP-Lite) under control of
the application’s firmware. Another option is to use the In-Circuit Programming (ICP)
mechanism. This ICP system provides for programming through a serial clock- serial
data interface using a commercially available EPROM programmer which supports
this device. This device does not provide for direct verification of code memory
contents. Instead this device provides a 32-bit CRC result on either a sector or the
entire 1 kB of user code space.
9.26.5
In-circuit programming (ICP)
In-Circuit Programming is performed without removing the microcontroller from the
system. The In-Circuit Programming facility consists of internal hardware resources
to facilitate remote programming of the P89LPC912/913/914 through a two-wire
serial interface. The Philips In-Circuit Programming facility has made in-circuit
programming in an embedded application, using commercially available
programmers, possible with a minimum of additional expense in components and
circuit board area. The ICP function uses five pins. Only a small connector (with V
DD
,
V
SS
, RST, clock, and data signals) needs to be available to interface your application
to a commercial programmer in order to use this feature. Additional details may be
found in the P89LPC912/913/914 User’s Manual
9.26.6
In-application programming (IAP-Lite)
In-Application Programming is performed in the application under the control of the
microcontroller’s firmware. The IAP-Lite facility consists of internal hardware
resources to facilitate programming and erasing. The Philips In-Application
Programming Lite has made in-application programming in an embedded application
possible without additional components. This is 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 P89LPC912/913/914 User’s Manual
9.26.7
Using flash as data storage
The Flash code memory array of this device supports
individual
byte erasing and
programming. Any byte in the code memory array may be read using the MOVC
instruction, provided that the sector containing the byte has not been secured (a
MOVC instruction is not allowed to read code memory contents of a secured sector).
Thus any byte in a non-secured sector may be used for non-volatile data storage.
9.26.8
User configuration bytes
Some user-configurable features of the P89LPC912/913/914 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
P89LPC912/913/914 User’s Manualfor additional details.
9.26.9
User sector security bytes
There are four User Sector Security Bytes, each corresponding to one sector. Please
see the P89LPC912/913/914 User’s Manualfor additional details.
