I have a MSC1213Y5- viz a Precision data converter with a high speed 8051 core. I have it raw. Now, I want to program it. I have an idea of what Bootloader is. The datasheet says the MCU has 2kB of boot ROM and also that I can the program the Flash through USART0 by pulling PSEN low and ALE high. There is also a list of instruction named as bootloader routines.
My question is whether the bootloader is already burnt in the bootROM or should I do it? How to do it? and what are these bootloader routines? Thanks in advance.
