Parallel Port Microprocessors
When interfacing the LTC1290 to an MPU which has a
parallel port, the serial signals are created on the port with
software. Three MPU port lines are programmed to create
the CS, SCLK and D
IN
signals for the LTC1290. A fourth
port line reads the D
OUT
line. An example is made of the
Intel 8051/8052/80C252 family.
Intel 8051
To interface to the 8051, the LTC1290 is programmed for
MSB-first format and 12-bit word length. The 8051 gener-
ates CS, SCLK and D
IN
on three port lines and reads D
OUT
on the fourth.
