Register 75: Synchronous Serial Interface Software Reset (SRSSI), offset
0x51C
The SRSSI register provides software the capability to reset the available SSI modules.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SRSSI register. While the SRSSI bit is 1, the peripheral is
held in reset.
2. Software completes the reset process by clearing the SRSSI bit.
There may be latency from the clearing of the SRSSI bit to when the peripheral is ready for use.
Software should check the corresponding PRSSI bit to verify that the SSI Module registers are ready
to be accessed.
Important: This register should be used to reset the SSI modules.

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.
