Hello,

just 2 quick (dumb) questions :)
- 14.7.5 SSP Clock Prescale Register -- 'In Slave mode, the SSP clock rate provided by the master must not exceed 1/12 of the SSP peripheral clock...' -- does this mean that when my LPC is running on 72 MHz, then maximum clock (SCK) in SPI slave mode can be 6 MHz? (~ 6 Mbit, 0.75 MB/s)

- does the SPI CS line have to toggle (go H and L) for every received byte in SPI slave mode? (found somewhere here, on forum).
