Legacy-Free Keyboard/Embedded Controller with SPI and LPC Docking Interface

The timeout interrupt is activated when there is a least one byte in the Rx FIFO, and neither the CPU

nor the Rx shift register has accessed the Rx FIFO within 4 character times of the last byte. The timeout

interrupt is cleared or reset when the CPU reads the Rx FIFO or another character enters it.

These FIFO related features allow optimization of CPU/UART transactions and are especially useful

given the higher baud rate capability (256 kbaud).
