MSP-FET430P140 Demo - USART0, SPI Interface to HC165/164 shift Registers
Description: Demonstrate USART0 in two-way SPI mode. Data are read from
an HC165, and same data written back to the HC164.
ACLK = n/a MCLK = SMCLK = default DCO = UCLK0 = DCO/2
* USART0 control bits are in different SFR s from other MSP430 s *
Top module name : shiftER (File name : shiftER.v)
2. Input pins: shift [3:0], IN [15:0], SIGN, RIGHT.
3. Output pins: OUT [15:0].
4. Input signals generated from test pattern are latched in one cycle and are
synchronized at clock rising edge.
5. The shift signal describes the shift number. The shift range is 0 to 15.
6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it
shifts input data to left.
7. When the signal SIGN is high, the input data is a signed number and it shifts with
sign extension. However, the input data is an unsigned number if the signal SIGN
is low.
8. You can only use following gates in Table I and need to include the delay
information (Tplh, Tphl) in your design.

This m file simulates a differential phase shift keyed (DPSK) ultra wide bandwidth(UWB) system using a fifth derivative waveform equation of a Gaussian pulse.
