registers (to be able to restart the interrupted operation later), and then it must be cleared
to prepare it for the new calculation. After the completion of the new division or
multiplication the state of the interrupted multiply or divide operation must be restored.
The MDRIU flag is the only portion of the MDC register which might be of interest to the
user. The remaining portions of the MDC register are reserved for dedicated use by the
hardware, and should never be modified by the user in any way other than described
above. Otherwise a correct continuation of an interrupted multiply or divide operation
cannot be guaranteed.
The Constant Zeros Register ZEROS
All bits of this bit-addressable register are fixed to ‘0’ by hardware. This register can be
read only. The ZEROS register can be used as a register-addressable constant of all
zeros, i.e. for bit manipulation or mask generation. It can be accessed via any instruction
which is capable of addressing an SFR.

The Constant Ones Register ONES
All bits of this bit-addressable register are fixed to ‘1’ by hardware. This register can be
read only. The ONES register can be used as a register-addressable constant of all
ones, i.e. for bit manipulation or mask generation. It can be accessed via any instruction
which is capable of addressing an SFR.

Note: Register SYSCON cannot be changed after execution of the EINIT instruction.
Identification Register Block
All new derivatives of 16-bit microcontrollers provide a set of identification registers that
offer information on the HW-status of the chip.The ID registers are read only registers.
They are placed in the extended SFR area.
