System Configuration Register (CONFIG)

The System Configuration Register can be used to determine the operational state of the ICACHE. If the

ICACHE is not functioning, the CACHEPRES bit of the CONFIG register will be cleared. If the ICACHE is

functioning normally, this bit will be set.

The System Configuration Register bit layout is shown in Figure 3−49 and the bits are described in Table 3−53.
