S
CREEN CONFIGURATION
The default value for L is logic 0. In the event of L = 0 the
two halves of a split screen are connected in a standard
way i.e. column 1/61, 2/62 to 60/120. In the event of L = 1
the two halves of a split screen are connected in a mirrored
way i.e. column 1/120, 2/119 to 60/61. This allows single
layer PCB or glass layout.
8.12.6
D
ISPLAY CONFIGURATION
The default value for P and Q is logic 0. P = 1 mirrors the
column data whereas Q = 1 mirrors the row data.

EDUCING CURRENT CONSUMPTION
Reducing current consumption can be achieved by one of
the options mentioned in Table 10.

INTERFACE TO MICROCONTROLLER
9.1
Parallel interface
The PCF2103 can send data in either two 4-bit operations
or one 8-bit operation and can thus interface to 4-bit or
8-bit microcontrollers.
In 8-bit mode data is transferred as 8-bit bytes using the
8 data lines DB7 to DB0. Three further control lines E, RS
and R/W are required; see Table 1.
In 4-bit mode data is transferred in two cycles of 4 bits
each using pins DB7 to DB4 for transaction. The higher
order bits (corresponding to DB7 to DB4 in 8-bit mode) are
sent in the first cycle and the lower order bits (DB3 to DB0
in 8-bit mode) in the second. Data transfer is complete
after two 4-bit data transfers. Note that two cycles are also
required for the busy flag check. 4-bit operation is selected
by instruction. See Figs 11 to 14 for examples of bus
protocol.
In 4-bit mode pins DB3 to DB0 must be left open-circuit.
They are pulled up to V
DD
internally.
