// #1: ;KCPSM3 Program - SPI Control of Amplifier and A/D converter on Spartan-3E Starter Kit.

// #6: ;Version v1.00 - 21th December 2005

// #8: ;This program uses an 8KHz interrupt to generate test waveforms on the
// #9: ;4 analogue outputs provided by the Linear Technology LTC2624 device.
// #10: ;
// #11: ;As well as the port connections vital to communication with the UART and the SPI
// #12: ;FLASH memory, there are additional port connections used to disable the other
// #13: ;devices sharing the SPI bus on the Starter Kit board. Although these could have been
// #14: ;controlled at the hardware level, they are included in this code to aid
// #15: ;future investigations of communication with the other SPI devices using PicoBlaze.
// #16: ;
// #17: ;Connections to the LEDs, switches and press buttons are provided to aid
// #18: ;development and enable further experiments. Otherwise know as having fun!
