Although VBAK may be connected to VSS, this is not
recommended if the companion is used. None of the
companion functions will operate below about 2.5V.
Note: systems using lithium batteries should clear
the VBC bit to 0 to prevent battery charging. The
VBAK circuitry includes an internal 1 K
series
resistor as a safety element.
Register Map
The processor companion functions are accessed via 16 special function registers that are mapped to a separate 2-
wire device ID. The interface protocol is described below. The registers contain control bits, or information flags. A
description of each register follows.

*Note that the usable address range starts at address 09h to preserve software compatibility with the FM31xx
device family, which includes a real-time clock in registers 00-08h.
Note: When the device is first powered up and programmed, all registers must be written because the battery-
backed register values cannot be guaranteed. The table below shows the default values of the non-volatile
registers. All other register values should be treated as unknown.
