+ * BadgePAD 4 Details
+ *
+ * PCM Vcc:
+ *
+ * PCM Vcc on BadgePAD 4 can be jumpered for 3v3 (short pins 1 and 3
+ * on JP6) or 5v0 (short pins 3 and 5 on JP6).
+ *
+ * PCM Vpp:
+ *
+ * PCM Vpp on BadgePAD 4 can be jumpered for 12v0 (short pins 4 and 6
+ * on JP6) or tied to PCM Vcc (short pins 2 and 4 on JP6). N.B.,
+ * 12v0 operation requires that the power supply actually supply 12v0
+ * via pin 7 of JP7.
+ *
+ * CF Vcc:
+ *
+ * CF Vcc on BadgePAD 4 can be jumpered either for 3v3 (short pins 1
+ * and 2 on JP10) or 5v0 (short pins 2 and 3 on JP10).
+ *
+ * Unfortunately there's no way programmatically to determine how a
+ * given board is jumpered. This code assumes a default jumpering
+ * as described below.
+ *
+ * If the defaults aren't correct, you may override them with a pcmv
+ * setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
+ * tenths of volts; e.g. pcmv=33,120,50 indicates 3v3 PCM Vcc, 12v0
+ * PCM Vpp, and 5v0 CF Vcc.
