Chapter 8 Serial Communication Interface (SCIV3)
8.2
The SCI module has a total of two external pins.
8.2.1
The TXD pin transmits SCI (standard or infrared) data. It will idle high in either mode and is high
impedance anytime the transmitter is disabled.
8.2.2
The RXD pin receives SCI (standard or infrared) data. An idle line is detected as a line high. This input is
ignored when the receiver is disabled and should be terminated to a known voltage.
8.3
This subsection provides a detailed description of all the SCI registers.
8.3.1
The memory map for the SCI module is given in
address offset. The total address for each register is the sum of the base address for the SCI module and
the address offset for each register.
8.3.2
This subsection consists of register descriptions in address order. Each description includes a standard
register diagram with an associated figure number. Writes to reserved register locations do not have any
effect and reads of these locations return a 0. Details of register bit and field function follow the register
diagrams, in bit order.
