RAH (A3-A0 Address 0001) Write Only
High Order Row Address Register
Bit 0 of this register and RAL form the 9-bit Row Address Register
that selects the row to be converted. The L1 and L2 bits control two
open-drain outputs that can be used to drive LEDs.

CAL (A3-A0 Address 0010) Read/Write
Low Order Column Address Register
CAL is a read/write register. Writing to this address writes to the
low-order 8 bits of the 9-bit Column Address Register. The 9-bit
Column Address Register selects a column from 0 through 299.
Writing to CAL causes the analog-to-digital (A/D) converter to
begin digitizing its input. The input of the A/D converter is selected
by bits 7 and 6 of the CAH register. The user should wait until the
row capture is completed before writing to the CAL.
Reading from this address returns the output of the A/D converter.
After writing to CAL, the user should wait until A/D conversion
completes before reading the A/D converter.
