ASYNCHRONOUS COMMUNICATIONS ELEMENT
WITH 64-BYTE FIFOs AND AUTOFLOW CONTROL

enabling auto-RTS and auto-CTS (continued)
The receiver FIFO trigger level can be set to 1, 4, 8, or 14 bytes for the 16-byte mode and 1, 16, 32, or 56 bytes
for 64-byte mode (see Figure 3).

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. This applies for external input and bidirectional buffers. VI > VCC does not apply to fail safe terminals.
2. This applies for external output and bidirectional buffers. VO > VCC does not apply to fail safe terminals.
