IAP - ability of a flash '51 to program its own flash from the running user application ISP - ability to program the flash '51 from an externl host via some few-lines serial line (SPI, UART, JTAG). Strictly speaking, one can in-situ program also using parallel programming, but as it ears up most of the chips pins, it is highly inconvenient (read: nobody does it this way) ICP - (in-circuit programming) Philips' attempt to make the picture even less clear, by introducing an abbeviation that can be messed up with the previous two so easily. Refers to ISP using SPI in the LPC9xx family (ISP then refers to UART-ISP, some of the LPC9xx are capable of both). ISP and IAP are not related directly, but as ISP is more common, practically all IAP-enabled '51 are ISP-able. It is not true other way round, e.g. the AT89Sxx family is SPI-ISPable, but don't feature IAP.
