42.6.2.1 Initialization

The following PDEC registers are enable-protected, meaning they can only be written when the PDEC is disabled (CTRLA.ENABLE is zero):

• Event Control register (EVCTRL)

Enable-protected bits in the CTRLA register can be written at the same time as CTRLA.ENABLE is written to '1', but not at the same time as CTRLA.ENABLE is written to '0'.

Enable-protection is denoted by the 'Enable-Protected' property in the register description.
