DS1863存儲(chǔ)器速查指南

作者: 時(shí)間:2011-05-28 來(lái)源:網(wǎng)絡(luò) 收藏
摘要:DS1863突發(fā)模式PON控制器集成了監(jiān)測(cè)電路,可用于配置報(bào)警、預(yù)警、查找表及其它功能。為了實(shí)現(xiàn)這些編程功能,需要一個(gè)大容量的映射寄存器,本應(yīng)用筆記介紹了寄存器圖的概況,便于器件的編程設(shè)計(jì)。

DS1863的存儲(chǔ)器

DS1863具有6個(gè)獨(dú)立的存儲(chǔ)器表,在內(nèi)部排列成8個(gè)字節(jié)行(圖1)。
  1. 地址從00h到7Fh的低層存儲(chǔ)器:它包含報(bào)警門限、預(yù)警門限、標(biāo)志、屏蔽和幾個(gè)控制寄存器,另外還包括密碼輸入?yún)^(qū)域(PWE)和表選擇字節(jié)。
  2. 表01h主要包括用戶EEPROM (PW1級(jí)訪問權(quán)限) 和一些報(bào)警、預(yù)警狀態(tài)字節(jié)。
  3. 表02h是多功能區(qū),包括配制寄存器、比例調(diào)節(jié)與失調(diào)數(shù)值、密碼、中斷寄存器以及各種控制字節(jié)。
  4. 表03h是嚴(yán)格的用戶EEPROM區(qū)域,受PW2級(jí)加密保護(hù)。
  5. 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(zhǎng)進(jìn)行設(shè)置。這些寄存器的訪問受PW2級(jí)加密保護(hù)。
  6. 表05h包含另一個(gè)LUT,允許APC設(shè)置點(diǎn)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(xiàng),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(jí)加密保護(hù)。

寄存器參考值

以下表格給出了低層存儲(chǔ)器、表01h和表02h的簡(jiǎn)單參考值,有關(guān)每位功能的說(shuō)明,請(qǐng)參考DS1863數(shù)據(jù)資料中對(duì)應(yīng)的寄存器。表03h、04h和05h不需要單獨(dú)的參考值,這里沒有列出。

注:RSVD是“RESERVED”的縮寫。
