S1C63466 TECHNICAL MANUAL
CHAPTER 1: OUTLINE
1.5 Mask Option
Mask options shown below are provided for the S1C63466. Several hardware specifications are prepared
in each mask option, and one of them can be selected according to the application. The function option
generator winfog, that has been prepared as the development software tool of S1C63466, is used for this
selection. Mask pattern of the IC is finally generated based on the data created by the winfog. Refer to the
"S5U1C63000A Manual" for the winfog.
<Functions selectable with S1C63466 mask options>
(1) External reset by simultaneous LOW input to the input port (K00–K03)
This function resets the IC when several keys are pressed simultaneously. The mask option is used to
select whether this function is used or not. Further when the function is used, a combination of the
input ports (K00–K03), which are connected to the keys to be pressed simultaneously, can be selected.
Refer to Section 2.2.2, "Simultaneous low input to terminals K00–K03", for details.
(2) Time authorize circuit for the simultaneous LOW input reset function
When using the external reset function (shown in 1 above), using the time authorize circuit or not can
be selected by the mask option. The reset function works only when the input time of simultaneous
LOW is more than the rule time if the time authorize circuit is being used.
Refer to Section 2.2.2, "Simultaneous low input to terminals K00–K03", for details.
(3) Input port pull-up resistor
The mask option is used to select whether the pull-up resistor is supplemented to the input ports or
not. It is possible to select for each bit of the input ports. When using the QFP5-128pin package, "With
pull-up resistor" option should be chosen for the K12 input port.
Refer to Section 4.4.3, "Mask option", for details.
(4) Output specification of the output port
Either complementary output or N-channel open drain output can be selected as the output specifica-
tion for the output ports R10–R13 and R20–R23. The selection is done in 4-bit units (R10–R13 and R20–
R23). The output ports R00–R03 can only be used as complementary output.
Refer to Section 4.5.2, "Mask option", for details.
(5) Output specification / pull-up resistor of the I/O ports
Either complementary output or N-channel open drain output can be selected as the output specifica-
tion when the P10–P13 and P20–P23 are in the output mode. The selection is done in 1-bit units or 4-
bit units depending on the I/O port.
1-bit unit: P20, P21, P22, P23
4-bit unit: P10–P13
Note that the P00–P03 can only be used as complementary output.
Further, whether or not the pull-up resistors working in the input mode are supplemented can be
selected. The selection is done in 1-bit units or 4-bit units depending on the I/O port.
1-bit unit: P20, P21, P22, P23
4-bit unit: P10–P13
Refer to Section 4.6.2, "Mask option", for details.
(6) LCD drive bias
Either the internal power supply (1/4 bias) or an external power supply (1/5 bias) can be selected as
the LCD system power supply.
Refer to Section 4.7.3, "Mask option", for details.
