ADS8681 SPI 指令送出順序及配置流程

Other Parts Discussed in Thread: ADS8681, ADS8689

您好

我這邊客戶需求要配置ADS8681 進行取樣

想要請教關於Single Device: Standard SPI Interface I指令送出
舉例而言
1 .配置SPI 介面協議為Standard SPI with CPOL = 0 and CPHASE = 1
依據datasheet Page 42 表5 , 這邊指出送出指令的前墜字元,及配置寫入讀取的記憶體位置
根據文內顯示,供給電源後第一個指令需要寫入SDI_CTL_REG Register(address=0x08),預計寫入資料32位元為0x0000 0001 資料內容

與上文的表五相比較後,其寫入字元為16 Bit,是否輸入為0b11010_10_000001000_0000,0000,0000,0001
2.配置輸入範圍+-2.5V
依據datasheet page 53,RANGE_SEL_REG Register (address = 14h)
與上文的表五相比較後,其寫入字元為16 Bit,是否輸入為0b11010_10_0,0001,0100_0000,0000,0000,0001

或是我理解有錯誤的地方,請指正謝謝
