General description
In addition to receiving and transmitting data, this interface converts it from serial to parallel
format and vice versa, using either an interrupt or polled handshake. The interrupts are
enabled or disabled by software. The interface is connected to the I
(SDAI) and by a clock pin (SCLI). It can be connected both with a standard I
