4 core clock periods
EE1 (output)
Synchronous to Core clock
1 core clock period
The core clock is the SC140 core clock. The ratio between the core clock and CLKOUT is configured during power-on-reset.
Refer to Table 1-4 on page 1-6 for details on EE pin functionality.
Figure 28 shows the signal behavior of the EE pins.
