1) Bit-addressable special function registers
2) This special function register is listed repeatedly since some bits of it also belong to other functional blocks.
3) “X” means that the value is undefined and the location is reserved. “U” means that the value is unchanged by
4) SFR is located in the mapped SFR area. For accessing this SFR, bit RMAP in SFR SYSCON must be set.
5) The notation “n” (n= 1 to F) in the message object address definition defines the number of the related
message object.
a reset operation. “U” values are undefined (as “X”) after a power-on reset operation
