The INH pin is typically used as a power supply enable for the system. Because INH is a logic high in standby and normal mode, and low in sleep mode, this is used to shut off the entire system into low-power mode via the transceiver sleep mode. When INH is disabled in sleep mode, the pin actually goes into a high-impedance state, not driven low. This can cause the INH high-voltage output to discharge slowly if the device it is connected to does not have a strong path to ground. Populating the shunt on J14 applies a stronger pull-down resistance to INH, forcing the voltage to discharge quickly when the function is disabled. The INH pin can be accessed via TP10, or J14.
