Re: LPC2130

Hi Karl,

the User's Manual has been posted in the file section (by John).

The 2132 and 2131 have an extra Flash area for the boot loader. 64k /
32k are all available to the user.

SSP Fifo 16 messages (see UM), data length any value between 4-bit and
16-bit.

Why not changed both SPI to SSP, legacy / compatibility. The old SPI
let's you switch between master and slave mode on the fly, the SSP
sort of does not. This feature is not typical in SPI usage but..  some
people might use / want it.

Hope these answers help.

Robert
