5.2.1 Clock Enable Control for eCAPx Modules
Each of the ECAPx modules have a clock enable (ECAPxENCLK). These signals need to be generated
from a device-level control register. When SYS_nRST is active low, the clock enables are ignored and the
ECAPx logic is clocked so that it can reset to a proper state. When SYS_nRST goes in-active high, the
state of clock enable is respected.
