S3C2410A同S3C2410X的區(qū)別! |
| 作者：weilong103 欄目：ARM技術(shù) |
S3C2410X to S3C2410A Revision Points Clock Divide: S3C2410X: HCLK is used same clock of Normal & Idle Mode.(1:2:4) S3C2410A:Idle Mode can used HCLK orHCLK/2.(Normal 1:2:4 → Idle 1:4:4) NOTE:Core & SYSTEM Bus POWER consumption are reduced about 30%. ADC: S3C2410X: LSB bit=0 is stuck. S3C2410A: Can use 10-bit ADC. SDIO: S3C2410X:S3C2410X MMC Card is operating speed Max 10MHZ.(MMC Spec: Max 20MHZ) S3C2410A:MMC Card is operating speed SUPPORT Max. 20MHZ.* Register SDICON bit[0] function changed Note:REFER to S3C2410A User's Manual. NOR:pagemode operating of INTEL OR FLASH sometimes error occurred. 2410A:SUPPORT Page Mode GSTATUS1Register (Chip ID):S3C2410X:0x32410000 2410A:0x32410002 |
