Remarks
Setting to 1 masks RF
communication detect
interrupt (including write detect
interrupts), regardless of the
system area HW2 parameter's
IRQSEL setting.
Setting to 1 masks
magnet-field detect interrupt,
regardless of the system area
HW2 parameter's IRQSEL
setting.
Setting to 1 disables RF
communication temporarily.
