; * Overview: The USB specifications allow some types of USB
; * peripheral devices to wake up a host PC (such
; * as if it is in a low power suspend to RAM state).
; * This can be a very useful feature in some
; * USB applications, such as an Infrared remote
; * control receiver. If a user presses the "power"
; * button on a remote control, it is nice that the
; * IR receiver can detect this signalling, and then
; * send a USB "command" to the PC to wake up.
; *
; * The USBCBSendResume() "callback" function is used
; * to send this special USB signalling which wakes
; * up the PC. This function may be called by
; * application firmware to wake up the PC. This
; * function should only be called when:
; *
; * 1. The USB driver used on the host PC supports
; * the remote wakeup capability.
; * 2. The USB configuration descriptor indicates
; * the device is remote wakeup capable in the
; * bmAttributes field.
; * 3. The USB host PC is currently sleeping,
; * and has previously sent your device a SET
; * FEATURE setup packet which "armed" the
; * remote wakeup capability.
; *
; * This callback should send a RESUME signal that
; * has the period of 1-15ms.
; *
; * Note: Interrupt vs. Polling
; * -Primary clock
; * -Secondary clock ***** MAKE NOTES ABOUT THIS *******
; * > Can switch to primary first by calling USBCBWakeFromSuspend()
; * The modifiable section in this routine should be changed
; * to meet the application needs. Current implementation
; * temporary blocks other functions from executing for a
; * period of 1-13 ms depending on the core frequency.
; *
; * According to USB 2.0 specification section 7.1.7.7,
; * "The remote wakeup device must hold the resume signaling
; * for at lest 1 ms but for no more than 15 ms."
; * The idea here is to use a delay counter loop, using a
; * common value that would work over a wide range of core
; * frequencies.
; * That value selected is 1800. See table below:
; * ==========================================================
; * Core Freq(MHz) MIP RESUME Signal Period (ms)
; * ==========================================================
; * 48 12 1.05
; * 4 1 12.6
; * ==========================================================
; * * These timing could be incorrect when using code
; * optimization or extended instruction mode,
; * or when having other interrupts enabled.
; * Make sure to verify using the MPLAB SIM's Stopwatch
; * and verify the actual signal on an oscilloscope.
