* BadgePAD 4 Details
*
* PCM Vcc:
*
* PCM Vcc on BadgePAD 4 can be jumpered for 3.3V (short pins 1 and 3
* on JP6) or 5V (short pins 3 and 5 on JP6). N.B., 5V supply rail
* is enabled by the SA-1110's BADGE4_GPIO_PCMEN5V (GPIO 24).
*
* PCM Vpp:
*
* PCM Vpp on BadgePAD 4 can be jumpered for 12V (short pins 2 and 4
* on JP6) or tied to PCM Vcc (short pins 4 and 6 on JP6). N.B., 12V
* operation requires that the power supply actually supply 12V.
*
* CF Vcc:
*
* CF Vcc on BadgePAD 4 can be jumpered either for 3.3V (short pins 1
* and 2 on JP10) or 5V (short pins 2 and 3 on JP10). The note above
* about the 5V supply rail applies.
*
* There's no way programmatically to determine how a given board is
* jumpered. This code assumes a default jumpering: 5V PCM Vcc (pins
* 3 and 5 shorted) and PCM Vpp = PCM Vcc (pins 4 and 6 shorted) and
* no jumpering for CF Vcc. If this isn't correct, Override these
* defaults with a pcmv setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf
* vcc>. E.g. pcmv=33,120,50 indicates 3.3V PCM Vcc, 12.0V PCM Vpp,
* and 5.0V CF Vcc.
