這是為了跟最早期的 PIC16C5x Code Protected 相容，所以只有最小的4-bit 可以被讀出來。這是IC 設計的規格只有跟著它的規範來使用啦。

您好:
小弟在讀pic16f8x data sheet時有點疑問,請問為何ID原廠只建議 只用4BIT,謝謝.原文如下 2.2 ID Locations A user may store identification information (ID) in four ID locations, mapped in addresses 2000h through 2003h. It is recommended that the user use only the four Least Significant bits of each ID location. The ID locations read out in an unscrambled fashion after code protection is enabled. It is recommended that ID location is written as “11 1111 1000 bbbb”, where “bbbb” is ID information.
