17.8.5.4
The MMCSMSCRD and the MMCSMSCR are the same registers accessed at two different addresses.
Reading or writing to one of these two addresses has exactly the same effect.
The duplication of the SCR register allows coherent 32-bit accesses when using a RCPU.
17.8.5.5
The status/control register (SCR) is a collection of read-only signal status bits, read/write control bits and
an 8-bit read/write data register, as detailed below.

The user should not write directly to the address of the MMCSMSCRD.
This register’s address may be reserved for future use and should not be
accessed by the software to ensure future software compatibility.

Modulus latches — These bits are read/write data bits containing the 16-bit modulus value to be
loaded into the up-counter.
The value loaded in this register must be the one’s complement of the desired modulus count.
The up-counter increments from this one’s complement value up to 0xFFFF to get the correct
number of steps before an overflow is generated to reload the modulus value into the up-counter.
