The Clock Synchronous Serial Interfaces 0,1 (CSIn, n=0,1) are two serial ports that transmit
8-bit data synchronized with internal or external clock signals.
Figure 9.1 gives a block diagram for Clock Synchronous Serial Interfaces 0,1 (CSIn, n=0,1).
The two have identical structures. Each includes the following components:
Overview
Block Diagram
- CSI Control Register (CSInCON, n=0,1), which controls transmission and reception
- CSI Shift Register (CSnSFT, n=0,1), which shifts the transmitted and received data
- CSI Status Register (CSInST, n=0,1), which indicates transfer status
