SHIFTOUT
Dpin, Cpin, Mode, [ OutputData {\Bits} {,OutputData {\Bits}…} ]
Function
Shift data out to a synchronous serial device.
•
Dpin
is a variable/constant/expression (0 – 15) that specifies the I/O
pin that will be connected to the synchronous serial device’s data
input. This pin will be set to output mode.
•
Cpin
is a variable/constant/expression (0 – 15) that specifies the I/O
pin that will be connected to the synchronous serial device’s clock
input. This pin will be set to output mode.
•
Mode
is a variable/constant/expression (0 – 1), or one of two
predefined symbols, that tells SHIFTOUT the order in which data
bits are to be arranged. See Table 5.92 for value and symbol
definitions.
•
OutputData
is a variable/constant/expression containing the data to
be sent.
•
Bits
is an optional variable/constant/expression (1 – 16) specifying
how many bits are to be output by SHIFTOUT. If no Bits entry is
given, SHIFTOUT defaults to 8 bits.

Explanation
SHIFTIN and SHIFTOUT provide an easy method of acquiring data from
synchronous serial devices. Synchronous serial differs from asynchronous
serial (like SERIN and SEROUT) in that the timing of data bits (on a data
line) is specified in relationship to clock pulses (on a clock line). Data bits
may be valid after the rising or falling edge of the clock line. This kind of
serial protocol is commonly used by controller peripherals like ADCs,
DACs, clocks, memory devices, etc.
