Register 76: Inter-Integrated Circuit Software Reset (SRI2C), offset 0x520
The SRI2C register provides software the capability to reset the available I
2
C modules.
A peripheral is reset by software using a simple two-step process:
1. Software sets a bit (or bits) in the SRI2C register. While the SRI2C bit is 1, the peripheral is
held in reset.
2. Software completes the reset process by clearing the SRI2C bit.
There may be latency from the clearing of the SRI2C bit to when the peripheral is ready for use.
Software should check the corresponding PRI2C bit to verify that the I
2
C Module registers are ready
to be accessed.
Important: This register should be used to reset the I
2
C 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.
