STM32L476RC有两个bank，都是128K大小，每个bank分为64个page，每个page 2K大小。
bank1的page编号从0-63，bank2的page编号从256-319。
这边我们给大家简单介绍一下如何计算某个地址位于哪一个page页下，起始地址是0x08000000，且每个page大小是2K，也就是2048byte，计算公式分为两种情况：
第一种是地址位于bank1，例如地址0x08001800：
计算公式：page = (0x0x08001800-0x08000000)/2048 = 3
第二种是地址位于bank2，例如我们此例程选择的地址0x08031800，因为bank首页编码为page 256，所以计算的值要加上192，才是正确的page编码：
计算公式：page = (0x08031800-0x08000000)/2048 + 192 = 291
