7 title: Renesas RZ/G2L Port Output Enable for GPT (POEG)
10 - Biju Das <biju.das.jz@bp.renesas.com>
13 The output pins(GTIOCxA and GTIOCxB) of the general PWM timer (GPT) can be
14 disabled by using the port output enabling function for the GPT (POEG).
15 Specifically, either of the following ways can be used.
16 * Input level detection of the GTETRGA to GTETRGD pins.
17 * Output-disable request from the GPT.
18 * SSF bit setting(ie, by setting POEGGn.SSF to 1)
20 The state of the GTIOCxA and the GTIOCxB pins when the output is disabled,
21 are controlled by the GPT module.
