Description

SIO_SDA

Digital

Input/Output

Bi-directional data I/O line for digital programming and diagnostic interfaces:

 I2C interface: SDA open drain data line; external pull-up resistor is mandatory,

see Figure 18, Figure 19, and Figure 20.

 SPI interface: SIO bi-directional push-pull data line; external pull-up resistor is

optional,

see Figure 16 and Figure 17.
