111 * LTC2978 clears peak data whenever the CLEAR_FAULTS command is executed, which
112 * happens pretty much each time chip data is updated. Raw peak data therefore
113 * does not provide much value. To be able to provide useful peak data, keep an
114 * internal cache of measured peak data, which is only cleared if an explicit
