1.5 Mask Option
Mask options shown below are provided for the S1C63454. 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 S1C63454, 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 S1C63454 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.
