Registers and Programming
The CH7013A is a fully programmable device, providing for full functional control through a set of registers
accessed from the serial port. The CH7013A contains a total of 37 registers, which are listed in
Table15
and
described in detail under
Register Descriptions
. Detailed descriptions of operating modes and their effects are con-
tained in the previous section,
Functional Description.
An addition (+) sign in the Bits column below signifies that
the parameter contains more than 8 bits, and the remaining bits are located in another register.
