I am using a LPC2104 and I am trying to send some I2C data with my LPC2104 set as the master in transmit mode, without having to use the SI bit to vector an interrupt service to load the I2DAT register. In other words i want to load the I2DAT after the SI bit in I2CONSET, and not having to load it i...
