38.6.2.1 Initialization

The AC bus clock (CLK_AC_APB) is required to access the AC registers. This clock can be enabled in the MCLK - Main Clock module.

A generic clock (GCLK_AC) is required to clock the AC. This clock must be configured and enabled in the GCLK - Generic Clock Controller before using the AC.

Some registers are enable-protected, that is, they can only be written when the module is disabled.

The following register is enable-protected: The Event Control register (EVCTRL)

Enable-protection is denoted by the "Enable-Protected" property in each individual register description.
