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 ...

D169 Demo - DMA0 Repeated Burst to-from RAM, Software Trigger
Description A 32 byte block from 220h-240h is transfered to 240h-260h
using DMA0 in a burst block using software DMAREQ trigger.
After each transfer, source, destination and DMA size are
reset to inital software setting because DMA tran ...
