4.4.2.7 Mode 7: Single Triggered Continuous Pulse Generation
This mode is similar to mode 5 except that the counter generates con-
tinuous periodic pulses with programmable pulse interval and pulse-width
following the first active edge of GPTC_GATE. Once the first GPTC_GATE
edge triggers the counter, GPTC_GATE takes no effect until the soft-
ware-start is re-executed. Figure 37 illustrates the generation of two pulses
with a pulse delay of four and a pulse-width of three.

4.4.2.8 Mode 8: Continuous Gated Pulse Generation
This mode generates periodic pulses with programmable pulse interval
and pulse-width following the software-start. GPTC_GATE is used to en-
able/disable counting. When GPTC_GATE is inactive, the counter halts the
current count value. Figure 38 illustrates the generation of two pulses with
a pulse delay of four and a pulse-width of three.
