 		 #185989 - ISP sometimes supported with zero boot loader
Responding to: ???'s previous message
Erik Malund said:
That IAP means that "uart bootloader" already at the chip.
2) incorrect for ISP, yes, ISP means that a bootloader is there but, by NOT that is an "uart bootloader".
Erik

Except that ISP can mean programmable using JTAG/BDM/..., in which case there need not be any bootloader at all. The JTAG interface can even be used to download a suitable flash erase/program algorithm allowing a processor with zero internal code space to program an external flash memory.
