void tcc_disable_callback | ( | struct tcc_module *const | module, |
const enum tcc_callback | callback_type | ||

Disables callback.
Disables the callback function registered by the tcc_register_callback, and the callback will not be called from the interrupt routine. The function will also disable the appropriate interrupts.

void tcc_enable_callback | ( | struct tcc_module *const | module, |

Enables callback.
Enables the callback function registered by the tcc_register_callback. The callback function will be called from the interrupt handler when the conditions for the callback type are met. This function will also enable the appropriate interrupts.
