Serial Port Microprocessors
Most synchronous serial formats contain a shift clock
(SCLK) and two data lines, one for transmitting and one for
receiving. In most cases data bits are transmitted on the
falling edge of the clock (SCLK) and captured on the rising
edge. However, serial port formats vary among MPU
manufacturers as to the smallest number of bits that can
be sent in one group (e.g., 4-bit, 8-bit or 16-bit transfers).
They also vary as to the order in which the bits are
transmitted (LSB- or MSB-first). The following examples
show how the LTC1283 accommodates these differences.
National MICROWIRE (COP820C)
The COP820C transfers data MSB-first and in 8-bit incre-
ments. This is easily accommodated by setting the LTC1283
to MSB-first format and 10-bit word length. The data
output word is then received by the COP820C in one 8-bit
block and one 2-bit block.
