4.3.25. Oscillator test registers, SYS_TEST_OSCx

The oscillator test registers, SYS_TEST_OSC0 through to SYS_TEST_OSC7 provide 32-bit count values. The count increments at the frequency of the corresponding ICS307 programmable oscillator (OSC0 through to OSC7). The registers are set to zero by a reset.

Table 4.27 lists the SYS_TEST_OSCx registers address locations.
