微处理器开发 MSP-FET430P140 Demo - USART0, SPI Interface to HC165/164 Shift Registers Description: Demonstrate
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 ...

技术资料 LPC Interface介绍
LPC---Lower Pin Count Interface
由于LPC BUS 在设计中为7根必备信号线和6根可选信号线共13根,
比传统的ISA BUS (Industry Standard Architecture) 8bits 62PIN和 16bit 98PIN
的信号线少很多. 在设计可以用在低速外设上代替ISA BUS.
