function RPI_pinModeAlt(pin,ALTMode)
// Function to set the current mode of pin
//
// Calling Sequence
//  RPI_pinModeAlt(pin,ALTMode)
//
// Parameters
//  pin    : The pin number to read the voltage from. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
//  ALTMode: integer, from 0 to 7
//
// Description
//    This function sets the mode of the pin to either of the general GPIO (also set through RPI_pinMode function) or the alternatives available (not accessible through RPI_pinMode function).
//
//  ALTMode can take the following values:
//  <itemizedlist>
//  <listitem>0 : Input</listitem>
//  <listitem>1 : Output</listitem>
//  <listitem>2 : ALT5</listitem>
//  <listitem>3 : ALT4</listitem>
//  <listitem>4 : ALT0</listitem>
//  <listitem>5 : ALT1</listitem>
//  <listitem>6 : ALT2</listitem>
//  <listitem>7 : ALT3</listitem>
//  </itemizedlist>
//
//The list of Alternate functions of all the pins can be found on page 102 of the official documentation: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/BCM2835-ARM-Peripherals.pdf
