I would recommend that you read the reference manual regarding the GPIO peripheral and the GPIOTE peripheral. I've tried to explain the difference between the GPIO and GPIOTE peripheral here: devzone.nordicsemi.com/.../

What you point to as a channel is a GPIOTE configured TASK/EVENT, usually used in combination with a PPI channel and another peripheral (can be hooked up to any of our events, generated from any of our peripherals). This is in relation to how the nRF51x22 chip works, and it not directly related to bluetooth. Have a look at some of the examples (ppi_example/gpiote_example/pwm_example etc) in the SDK as well to see how it behaves.
