Does anyone know if there is a good reason why the pinout of the LPC1200 devices is entirely logical, but the pin allocations on LPC1100 devices appear to have been scattered completely randomly around the device?

For instance, I would have thought that all the SPI outputs would be in the same area of the silicon, but the pinouts are on pins 2, 13, 26 and 38; whereas on the LPC1200 they are on 14, 15, 16 and 17. Generally, all the tracks from the SPI pins head off in the same direction, so why are the pins all-over-the-place?
