conventional single-conversion superheterodyne receiver (fixed
mode) - this is the recommended mode of operation. This pin is
internally pulled-up to VCC.

detected.
Shutdown-mode logic-level control input. Pull low to enable the
receiver. Internally pulled-up to VCC.
16V supply input. Pulling this pin low disables module. In a non-
regulated module, this is a no connect.
In a regulated module, this is a 5V output from the onboard
regulator when REG-EN is high (2-16V). In a non-regulated
module, this is the 4.75V to 5.5V power supply input.
In a regulated module, this is the power supply pin of the module.
