6.3 Flash memory IAP
6.3.1 Flash organization
The P89V51RB2/RC2/RD2 program memory consists of a 16/32/64 kB block. 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 ash memory that may be used. First, the ash 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 bootloader may be invoked. This ISP bootloader will, in turn, call
low-level routines through the same common entry point that can be used by the end-user
application. Third, the ash may be programmed or erased using the parallel method by
using a commercially available EPROM programmer which supports this device.
6.3.2 Boot block (block 1)
When the microcontroller programs its own ash 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.
