INTERFACES

Serial interface features supported

The 4213 supports the following serial interface features:

Bit rate within a character may be up to 19.2K baud

Baud rates of 1,200, 2,400, 4,800, 9,600, 19,200

Character format: bit serial

Character asynchronous

Start bit (space)

7 or 8 data bits (1=mark, 0=space)

Optional parity bit

Stop bit (mark)

Data bits represent a character.

Least significant data bit leads

Number of bits and polarity of parity are selectable via the
User Interface.

Parity error is enabled only when even or odd parity is
selected.

Serial signals and pin assignments

Table 1-6 describes the signals and pin assignments used with
the asynchronous serial interface.
