Figure 43. A Sample Program for Data Collection from the
LTC2435/LTC2435-1 Using the PIC16F73 Microcontroller.
// Enable LTC2435
// Read first byte, send 2 hex characters.
// Read second byte, send 2 hex characters.
/ Read third byte, send 2 hex characters.
// Send carriage return.
// Conversion actually started after last data byte was read,
// but raising CS_ ensures the loop will never lock up waiting for
// a low on SDO if a clock pulse is missed for some reason.
