29 * BadgePAD 4 Details
30 *
31 * PCM Vcc:
32 *
33 * PCM Vcc on BadgePAD 4 can be jumpered for 3v3 (short pins 1 and 3
34 * on JP6) or 5v0 (short pins 3 and 5 on JP6).
35 *
36 * PCM Vpp:
37 *
38 * PCM Vpp on BadgePAD 4 can be jumpered for 12v0 (short pins 4 and 6
39 * on JP6) or tied to PCM Vcc (short pins 2 and 4 on JP6). N.B.,
40 * 12v0 operation requires that the power supply actually supply 12v0
41 * via pin 7 of JP7.
42 *
43 * CF Vcc:
44 *
45 * CF Vcc on BadgePAD 4 can be jumpered either for 3v3 (short pins 1
46 * and 2 on JP10) or 5v0 (short pins 2 and 3 on JP10).
47 *
48 * Unfortunately there's no way programmatically to determine how a
49 * given board is jumpered. This code assumes a default jumpering
50 * as described below.
51 *
52 * If the defaults aren't correct, you may override them with a pcmv
53 * setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
54 * tenths of volts; e.g. pcmv=33,120,50 indicates 3v3 PCM Vcc, 12v0
55 * PCM Vpp, and 5v0 CF Vcc.
