Description
General purpose output port.
General purpose output port.
General purpose output port.
General purpose output port.
General purpose output port.
May be used to control a switch which controls the RF transmit power.
For controlling whether the RF module runs on spread-spectrum or
narrowband.
Low speed clock oscillator for sleep control.
Low speed clock oscillator for sleep control.
Read strobe input for port AD, low = true.
Ring control output.
RSSI integrate/dump control.
Internal data path output to microcontroller.
Mute receive audio.
PN epoch sync for receive, transmit or both.
Not a user control. Hold high always.
Controls state of RF module transmit/receive switch.
Controls switch to disconnect audio from RF module modulation input
during receive part of TDD.
Internal data path input from microcontroller.
For disconnecting transmit audio when data must be transmitted.
Turns on RF module transmit power during transmit part of TDD, and
off during receive part of TDD.
Pseudo-noise sequence to RF module.
Causes chip phase control to step the phase. Used in conjunction with
ADVANCE pin 7.
DC power input = +VCC Volts.
Write strobe for Port AD. Low = true.
