P3 (RSV)
The on/off state of these systems is controlled by the serial
data.
Pin 9 : ILL illumination on/off control
Pin 10 : LCD illumination on/off control
Pins 19 and 20 : Used for other applications.

VCC100mA (AMP+B)
VCC100mA (ANT+B)
VCC-1V unstabilized outputs that can provide 100mA.
The on/off state of these outputs can be controlled with serial
data.
Used with the ANT+B and AMP+B systems.

CLK
DATA
LATCH
The serial data received over this serial interface controls the
outputs other than COM10V, CD5V, and VDD5V. It also
controls the on/off state of P1 to P4.
24
TP1 (5V)
Monitors the power supply used for the internal logic circuits
(the CLK, DATA, and LATCH inputs and on/off control).
