Serial Communication Interface (SCIV3)
8.1
This block description chapter provides an overview of serial communication interface (SCI) module.
The SCI allows full duplex, asynchronous, serial communication between the CPU and remote devices,
including other CPUs. The SCI transmitter and receiver operate independently, although they use the same
baud rate generator. The CPU monitors the status of the SCI, writes the data to be transmitted, and
processes received data.
8.1.1
IR: infrared
IrDA: Infrared Design Association
IRQ: interrupt request
LSB: least significant bit
MSB: most significant bit
NRZ: non-return-to-Zero
