请教各位高手,最近在学习VS1003,由于手头没有12.288M的晶振,就用了一个12M的晶振,根据VS1003的数据手册,将0X05寄存器写入数值为0x9BE8,但是在不播放128Kb以上码率的MP3文件时还是比较卡,请问高手这事什么原因了?
Example: If SCI CLOCKF is 0x9BE8, SC MULT = 4, SC ADD = 3 and SC FREQ = 0x3E8 = 1000.
This means that XTALI = 1000£4000+8000000 = 12 MHz. The clock multiplier is set to 3:0£XTALI =
36 MHz, and the maximum allowed multiplier that the firmware may automatically choose to use is
(3:0 + 1:5)£XTALI = 54 MHz. |
