7.2 Flash memory In-Application Programming
7.2.1
Flash organization
The P89V51RB2/RC2/RD2 program memory consists of a 16/32/64 kB block. An
In-System Programming (ISP) capability, in a second 8 kB block, is provided to allow
the user code to be programmed in-circuit through the serial port. There are three
methods of erasing or programming of the Flash memory that may be used. First, the
Flash may be programmed or erased in the end-user application by calling low-level
routines through a common entry point (IAP). Second, the on-chip ISP boot loader
may be invoked. This ISP boot loader will, in turn, call low-level routines through the
same common entry point that can be used by the end-user application. Third, the
Flash may be programmed or erased using the parallel method by using a
commercially available EPROM programmer which supports this device.
7.2.2
Boot block (Block 1)
When the microcontroller programs its own Flash memory, all of the low level details
are handled by code that is contained in Block 1. A user program calls the common
entry point in the Block 1 with appropriate parameters to accomplish the desired
operation. Boot block operations include erase user code, program user code,
program security bits, etc.
A Chip-Erase operation can be performed using a commercially available parallel
programer. This operation will erase the contents of this Boot Block and it will be
necessary for the user to reprogram this Boot Block (Block 1) with the
Philips-provided ISP/IAP code in order to use the ISP or IAP capabilities of this
device. Contact
