REV. 5.0.3
2.90V TO 5.5V UART WITH 32-BYTE FIFO
2.1.1
PC MODE
The PC mode interface includes an on-chip address decoder and interrupt selection function for the standard
PC COM 1-4 port addresses. The selection is made through three input signals: S1, S2 and S3. The selection
summary is shown in Table 1. Although the on-chip address decoder was designed for PC applications
ranging from 0x278 to 0x3FF, it can fit into an embedded applications by offsetting the address lines to the
650A. An example is shown in Figure 5 where the UART is operating from 0x80F8 to 0x80FF address space.
Operating in the PC mode eliminates external address decode components.
