介紹
DS1865突發(fā)模式PON控制器內(nèi)置監(jiān)測電路。該器件具有七個獨立的存儲器表,內(nèi)部排列成8個字節(jié)行。此外,該控制器還具有輔助存儲器,這些存儲器為EEPROM,可通過A0h從地址讀取。DS1865存儲器圖
低層存儲器的地址從00h至7Fh。該存儲器包含報警、預(yù)警門限、標(biāo)志、屏蔽和幾個控制寄存器,密碼輸入?yún)^(qū)域(PWE)和表選擇字節(jié)。參見圖1。表01h主要包括EEPROM (PW1級訪問權(quán)限)和一些報警、預(yù)警狀態(tài)字節(jié)。
表02h是多功能區(qū),包括配置寄存器、比例調(diào)節(jié)與失調(diào)存儲器、密碼、中斷寄存器以及各種控制字節(jié)。
表03h是關(guān)鍵數(shù)據(jù)的用戶EEPROM區(qū)域,受PW2級加密保護(hù)。
表04h包含溫度索引查找表(LUT),用于控制調(diào)制電壓。調(diào)制LUT可以在-40°C至+102°C范圍內(nèi),以2°C步長進(jìn)行設(shè)置。這些寄存器的訪問受PW2級加密保護(hù)。
表05h包含另一個LUT,允許APC設(shè)置點作為溫度的函數(shù)進(jìn)行調(diào)節(jié),用于跟蹤誤差(TE)補(bǔ)償。TE LUT具有36項,能夠在-40°C至+100°C范圍內(nèi),以4°C為間隔設(shè)置APC。該寄存器的訪問受PW2級加密保護(hù)。
表06h包含一個MON4索引LUT,用于控制M4DAC電壓。M4DAC LUT具有32項,可配置為一個32項的LUT或兩個16項的LUT。當(dāng)配置為一個32項的LUT時,每一項對應(yīng)的步長為滿量程1/32。當(dāng)配置為兩個16項LUT時,前16項和后16項分別對應(yīng)滿量程的1/16。兩個16項都通過獨立的配置位進(jìn)行選擇。該寄存器的訪問受PW2級加密保護(hù)。

寄存器參考值
以下表格給出了低層存儲器、表01h和表02h的簡單參考值,有關(guān)每位功能的說明,請參考DS1865數(shù)據(jù)資料中對應(yīng)的寄存器。表03h、04h、05h和08h不需要單獨的參考值,這里沒有列出。(請參考數(shù)據(jù)資料了解這些表格的詳細(xì)信息。)注:RSVD是"Reserved”的縮寫。
