I/O RAM (Configuration RAM) – Alphabetical Order
Many functions of the chip can be controlled via the I/O RAM (Configuration RAM). The CE will also take some of its parameters
from the I/O RAM.
Bits with a W (write) direction are written by the MPU into I/O RAM. Typically, they are initially stored in flash memory and copied
to the I/O RAM by the MPU. Some of the more frequently programmed bits are mapped to the MPU SFR memory space. The
remaining bits are mapped to 2xxx. Bits with R (read) direction can only be read by the MPU. On power up, all bits are cleared
to zero unless otherwise stated. Generic SFR registers are not listed.

R/W
Must be 0.
COMP_INT[1:0]
2003[4:3]

create MPU interrupts. 1: interrupt, 0: no interrupt. If 11, the
comparator outputs are XOR’ed.
Bit0 = comp2, Bit1 = comp3
