Terminology
A ‘_N’ after a signal name refers to an active low signal, indicating that a signal is in the
asserted state when driven to a low level. For example, when RESET_N is low (that is,
when RESET_N is asserted), a reset has been requested. Conversely, when TCK is high
(that is, when TCK is asserted), a test clock request has occurred.
