Pin Description
XR16C854/854D
2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO
Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain.
Factory Test Mode
If the IOR#, IOW# and CS# pins are all asserted (at a logic 0) simultaneously, the 854 will enter a Factory Test
Mode. The 854 is not operational in this mode and will exit this mode only upon a power cycle.
