- :cpp:member:`pcnt_chan_config_t::invert_edge_input` 与 :cpp:member:`pcnt_chan_config_t::invert_level_input` 用于确定信号在输入 PCNT 之前是否需要被翻转，信号翻转由 GPIO 矩阵（不是 PCNT 单元）执行。
调用函数 :cpp:func:`pcnt_new_channel`，将 :cpp:type:`pcnt_chan_config_t` 作为输入值并调用 :cpp:func:`pcnt_new_unit` 返回的 PCNT 单元句柄，可对 PCNT 通道进行分配和初始化。如果该函数正常运行，会返回一个 PCNT 通道句柄。如果没有可用的 PCNT 通道（PCNT 通道资源全部被占用），该函数会返回错误 :c:macro:`ESP_ERR_NOT_FOUND`。可用的 PCNT 通道总数记录在 :c:macro:`SOC_PCNT_CHANNELS_PER_UNIT`，以供参考。注意，为某个单元安装 PCNT 通道时，应确保该单元处于初始状态，否则函数 :cpp:func:`pcnt_new_channel` 会返回错误 :c:macro:`ESP_ERR_INVALID_STATE`。

如果不再需要之前创建的某个 PCNT 通道，建议通过调用 :cpp:func:`pcnt_del_channel` 回收该通道，从而该通道可用于其他用途。
