20.3.5 Interrupt mask registers 0 to 5 (IMR0 to IMR5)
IMR3.xxMKn bits are equivalent to the xxICn.xxMKn bit.
register, these registers can be read or written in 8-bit or 1-bit units.
The IMR0 to IMR5 registers set the interrupt mask state for the maskable interrupts.
The IMRm register can be read or written in 16-bit units (m = 0 to 5).
If the higher 8 bits of the IMRm register are used as the IMRmH register and the lower 8 bits as the IMRmL
Reset sets these registers to FFFFH.
Caution The device file defines the xxICn.xxMKn bit as a reserved word. If a bit is manipulated using the
name of xxMKn, the contents of the xxICn register, instead of the IMRm register, are rewritten (as
a result, the contents of the IMRm register are also rewritten).
