ADV7160/ADV7162
Figure 33. MPU Port and Register Configuration
MICROPROCESSOR (MPU PORT)
The ADV7160/ADV7162 supports a standard MPU Interface.
All the functions of the part are controlled via this MPU port.
Direct access is gained to the Address Register, Mode Register
and all the Control Registers as well as the Color Palette. The
following sections describe the setup for reading and writing to
all of the devices registers.
MPU Interface
The MPU interface (Figure 33) consists of a bidirectional, 10-
bit wide databus and interface control signals
CE
, C0, C1 and
R
/W
. The 10-bit wide databus is user configurable as illustrated.

Register Mapping
The ADV7160/ADV7162 contains a number of on-board regis-
ters including the Mode Register (MR17–MR10), Address Reg-
ister (A10–A0) and many Control Registers as well as Color
Palette Registers. These registers control the entire operation of
the part. Figure 34 shows the internal register configuration.
Control lines C1 and C0 determine which register the MPU is
accessing. C1 and C0 also determine whether the Address Reg-
ister is pointing to the color registers and Look-Up Table RAM
or the control registers. If C1, C0 = 1, 0 the MPU has access to
whatever control register is pointed to by the Address Register
(A10–A0). If C1, C0 = 0, 1 the MPU has access to the Look-
Up Table RAM (Color Palette) or the Overlay Palette through
the associated color registers. The
CE
input latches data to or
from the part.
The R/
W
control input determines between read or write ac-
cesses. The truth tables show all modes of access to the various
registers and color palette for both the 8-bit wide databus con-
figuration and 10-bit wide data bus configuration. It should be
noted that after power-up, the devices MPU port is automati-
cally set to 10-bit wide operation (see Power-On Reset section).
Figure 32. 8-Bit Pseudo Color in 8:1 Multiplexing Mode
The unused Blue pixel inputs are used, in this mode, to provide
8 extra PS inputs. These PS inputs provide 2 bits after 8:1 mul-
tiplexing. The PS inputs can be used as Overlay or Palette Se-
lect inputs.
