4.
SFRs in this column are both bit and byte-addressable.
Complies to 80C51 family architecture specification.
These registers are read only (all other SFRs are read/write).
Reserved register, used for testing purposes. Writing of reserved or undocumented bits might lead to unexpected
behaviour of the device (see Section 10.8).
