Figure 3-6 Test chip I/O multiplexer logic
The IOMUX registers control the IOMUX multiplexer logic. The following table shows the IOMUX
registers in offset order from the SCC base memory address of
0x4010_C000
in the Non-secure region, or
0x5010_C000
in the Secure region.
Note
for the read/write access characteristics.
