Section 15 Serial I/O with FIFO (SIOF)
15.1
Overview
The serial I/O with FIFO functions mainly as an interface between the chip and a codec or modem
analog front-end.
15.1.1
Features
The serial I/O has the following features:
•
Full-duplex operation
Independent transmit/receive registers and independent transmit/receive clocks
•
Primary data transmit/receive FIFO/Double-buffered transmit/receive ports
Continuous data transmission/reception possible
•
Interval transfer mode and continuous transfer mode
•
Memory-mapped receive data register, transmit data register, serial control register, and serial
status register, receive control data register, transmit control data register, FIFO control
register, FIFO data count register
With the exception of SIRSR and SITSR, these registers are memory-mapped and can be
accessed by a MOV instruction.
•
Choice of 8- or 16-bit data length
•
Data transfer communication by means of polling or interrupts
Data transfer can be monitored by polling the receive data register full flag (RDRF), the
receive data register empty flag (RDRE), the receive control data register full flag (RCD), and
the transmit control data register empty flag (TCD). Interrupt requests can be generated during
data transfer by setting the receive interrupt request flag and the transmit interrupt request flag.
•
Either MSB-first or LSB transfer can be selected for data I/O operations.
Figure 15.1 shows a block diagram of the serial I/O with FIFO.
