Read-modify-write operations on the LATA register read and write the latched output value for PORTA. 理解LAT register 的 "memory mapped" 特性, 也应类似于这里的(软件)"跟随 flag" 的比拟特点. 5.2 LAT register 在 PIC16 亦获引入 gpio 原理框图见 PIC16(L)F1674 的 datasheet:数据锁存器 (L...
OF THE INVENTION A method and apparatus for a read-modify-write operation in a digital computer memory system which reduces memory data path buffer storage reguirements with a procedure which includes latching new write data and associated mask fields into a data output buffer and then merging ...
读来整个8个IO口的数据,修改某一位,然后再把整个8个IO口输出 GpioDataRegs.GPADAT.bit.GPIO1 = 1 ; GpioDataRegs.GPADAT.bit.GPIO2 = 1 如果GPIO1的输出接了一个大一点的电容 GpioDataRegs.GPADAT.bit.GPIO1 = 1 ; 输出1了但是电压还没有上升到高电平 紧接着运行 GpioDataRegs.GPADAT.bit.GPIO2 = 1 他...
