serial communications interface (SCI1 or SCI2)
The term SCI is used frequently to refer to SCI1 and SCI2. The SCI1 and SCI2 modules are built-in serial
interfaces. The SCI1 has a 3-pin configuration and SCI2 has a 2-pin configuration. Both offer the following
features:
Programmable to be asynchronous (up to 156 Kbps)
Full duplex, double-buffered receive (Rx) and transmit (Tx)
Programmable format with error-checking capabilities
The following feature is available only on the SCI1 module:
Programmable to be isosynchronous (up to 2.5 Mbps)
The SCI1 and SCI2 modules program and control all timing, data format, and protocol factors. The CPU takes
part in the serial communications only:
To write data transmitted to the registers in the SCI
To read received data from the registers in the SCI when interrupted
serial peripheral interface (SPI)
The SPI module is a built-in serial interface that facilitates communication between the network master, slave
CPUs, and the external peripheral devices. The SPI module provides synchronous data transmission of up to
2.5 Mbps. Like the SCI, the SPI is set up by software. Once setup, the CPU takes no part in timing, data format,
or protocol. Also, like the SCI, the CPU reads and writes to memory-mapped registers to receive and transmit
data. An SPI interrupt alerts the CPU when received data is ready.
analog-to-digital converter (ADC1, ADC2, ADC3) modules
The 8-bit
ADC
modules perform successive approximation conversion. The term ADC is a general term used
for ADC1, ADC2, and ADC3 modules. The ADCs offer the following number of input channels for each of the
specified microcontroller families:
ADC1 offers the following:
–
Four channels in the 40-pin devices of the ’x4x subfamily,
–
Eight channels in the 44-pin devices of the ’x4x, ’x32, and ’x36 subfamilies
–
Eight channels in the 64-pin and 68-pin devices of the ’x5x, ’x6x, ’x7x, and ’xBx subfamilies
ADC2 offers four channels in the 28-pin devices of the ’xCx subfamily
ADC3 offers 15 channels in the 40-pin and 44-pin devices of the ’x9x subfamily
The reference source and input channel are selectable. The user can program the conversion result to be the
ratio of the input voltage to the reference voltage or the ratio of one analog input to another. Input lines that are
not required for analog-to-digital conversion can be programmed to be digital input lines.
For a detailed explanation on any of the major components of the TMS370 device family, see the TMS370 8-Bit
Microcontroller User’s Guide(literature number SPNU127) or to the specific subfamily data sheet.
For more details on the programming of the TMS370 family or for further expansion on the applications of these
devices, see the paragraph in this section on related documentation from Texas Instruments.
