9.28.4 Flash programming and erasing
9.28.5 In-circuit programming (ICP)
Chip Erase operation will erase the entire program memory. In-Circuit Programming
using standard commercial programmers is available. In addition, In-Application
Programming (IAP-Lite) and byte erase allows code memory to be used for
non-volatile data storage. On-chip erase and write timing generation contribute to a
user-friendly programming interface. The P89LPC915/916/917 Flash reliably stores
memory contents even after 100,000 erase and program cycles. The cell is designed
to optimize the erase and programming mechanisms. The P89LPC915/916/917 uses
V
The P89LPC915/916/917 program memory consists of eight 256- byte sectors. Each
sector can be further divided into sixteen 16-byte pages. In addition to sector erase,
page erase, and byte erase, a 16-byte page register is included which allows from
1 to 16 bytes of a given page to be programmed at the same time, substantially
reducing overall programming time. In addition, erasing and reprogramming of
user-programmable configuration bytes including UCFG1, the Boot Status Bit, and
the Boot Vector is supported.
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 2 kB of user code space.
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 P89LPC915/916/917 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
