shadowed bits
Many of the control register bits are described as “shadowed”. This means that changing the value of one of
these bits does not take effect until the current conversion is complete.
serial peripheral interface (SPI) module
The F243/F241 devices include the four-pin serial peripheral interface (SPI) module. The SPI is a high-speed
synchronous serial I/O port that allows a serial bit stream of programmed length (one to sixteen bits) to be shifted
into and out of the device at a programmable bit-transfer rate. Normally, the SPI is used for communications
between the DSP controller and external peripherals or another processor. Typical applications include external
I/O or peripheral expansion through devices such as shift registers, display drivers, and ADCs. Multidevice
communications are supported by the master/slave operation of the SPI.
The SPI module features include the following:
D Four external pins:
SPISOMI: SPI slave-output/master-input pin
SPISIMO: SPI slave-input/master-output pin
SPISTE: SPI slave transmit-enable pin
SPICLK: SPI serial-clock pin
NOTE: All these four pins can be used as GPIO, if the SPI module is not used.
D Two operational modes: master and slave
D Baud rate: 125 different programmable rates/5 Mbps at 20-MHz CPUCLK
D Data word length: one to sixteen data bits
D Four clocking schemes controlled by clock polarity and clock phase bits include:
Falling edge without phase delay: SPICLK active high. SPI transmits data on the falling edge of the
SPICLK signal and receives data on the rising edge of the SPICLK signal.
Falling edge with phase delay: SPICLK active high. SPI transmits data one half-cycle ahead of the
falling edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal.
Rising edge without phase delay: SPICLK inactive low. SPI transmits data on the rising edge of the
SPICLK signal and receives data on the falling edge of the SPICLK signal.
Rising edge with phase delay: SPICLK inactive low. SPI transmits data one half-cycle ahead of the
falling edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal.
D Simultaneous receive and transmit operation (transmit function can be disabled in software)
D Transmitter and receiver operations are accomplished through either interrupt-driven or polled algorithms.
D Eight SPI module control registers: Located in control register frame beginning at address 7040h.
NOTE: All registers in this module are 16-bit registers that are connected to the 16-bit peripheral bus. When a register is accessed, the register
data is in the lower byte (7 0), and the upper byte (15 8) is read as zeros. Writing to the upper byte has no effect.
Figure 12 is a block diagram of the SPI in slave mode.
