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 transfer mode 5 is used. P1.0 is toggled durring DMA transfer only for demonstration purposes. ** RAM location 0x220 - 0x260 used - always make sure no compiler conflict ** ACLK= n/a, MCLK= SMCLK= default DCO ~ 800k

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 *
