原文:The 12-bit literal ‘k’ is loaded into the File Select Register pointed
to by ‘f’.
問題:pointed to by 'f'。
這邊應該是File Select Register which is pointed to by 'f'省略which is。
想請問可以這樣用嗎?兩個prep.放在一起?

'f' points to the File Select Register(被動)-> the File Select Register is pointed to by 'f'to 和 by 是分開看的，沒問題

謝謝。
