9 CTI Application Channel Clear register, CTIAPPCLEAR

The application channel clear register allows software to clear any channel output. This register can be used by software to clear a channel event in place of a hardware source on a trigger input. In a system where all events are sent as single cycle pulses, this register must not be used. It is only retained for compatibility with older systems and software. The register is implemented before the CTIGATE register so, for the channel event to propagate outside the CTI, it is necessary for the corresponding CTIGATE bit to be 1.
