Since Philips is strong in I2C, does anyone know
whether there are some I2C example code for the
LPC210x, like that published in the 8XC552 data

If during an I2C transaction (writing to a I2C display), I get a UART
interrupt that has a possible I2C transaction itself (writing 2 bytes to
I2C RAM), how do I handle that? ...
