MPR 3X-4X Register table · version current table, valid for firmware after 1.3.6
manufacturer register table

Only the measurement block (0-161) is mapped; the full table is in the MPR-3X / MPR-4X map.
Addresses are 0-based. The table does not state word order; high word first assumed. Not tested on a device.
