INSTRUCTIONS
Only two PCF2103 registers, the Instruction Register (IR)
and the Data Register (DR) can be directly controlled by
the microcontroller. Before internal operation, control
information is stored temporarily in these registers to allow
interface to various types of microcontrollers which
operate at different speeds or to allow interface to
peripheral control ICs. The format for instructions when
I
2
C-bus control is used is shown in Table 6. The PCF2103
operation is controlled by the instructions given in Table 7
together with their execution time. Details are explained in
subsequent sections.
Instructions are of 4 types, those that:
1.
Designate PCF2103 functions such as display format,
data length, etc.
2.
Set internal RAM addresses
3.
Perform data transfer with internal RAM
4.
Others.
In normal use, instructions that perform data transfer with
internal RAM are used most frequently. However,
automatic incrementing by 1 (or decrementing by 1) of
internal RAM addresses after each data write lessens the
microcontroller program load. The display shift in particular
can be performed concurrently with display data write,
enabling the designer to develop systems in minimum time
with maximum programming efficiency.
During internal operation, no instruction other than the
‘read busy flag and address counter’ instruction will be
executed. Because the busy flag is set to logic 1 while an
instruction is being executed, the user should verify that
the busy flag is at logic 0 before sending the next
instruction or wait for the maximum instruction execution
time, as given in Table 7. An instruction sent while the
busy flag is logic 1 will not be executed.
