Notes

Notes:

1. The min VILand max VIH values are based on the min and max DVIN respective values found in Table 3.

2. The symbol DVIN represents the input voltage of the supply. It is referenced in Recommended operating conditions.

3. For recommended operating conditions, see Table 3.

This table provides the DC electrical characteristics for the DUART interface at DVDD =

1.8 V.

Minimum baud rate

Maximum baud rate

Notes:

fPLAT/(2 x 1,048,576)

baud

1, 3

fPLAT/(2 x 16)

baud

1, 2

1. fPLAT refers to the internal platform clock.

2. The actual attainable baud rate is limited by the latency of interrupt processing.

3. The middle of a start bit is detected as the eighth sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values

are sampled each 16th sample.
