Register 47: Synchronous Serial Interface Peripheral Present (PPSSI), offset
0x31C
The PPSSI register provides software information regarding the SSI modules.
Important: This register should be used to determine which SSI modules are implemented on this
microcontroller. However, to support legacy software, the DC2 register is available. A
read of the DC2 register correctly identifies if a legacy SSI module is present. Software
must use this register to determine if a module that is not supported by the DC2 register
is present.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
