Caution If the total number of digits and segments exceeds 34, the specified number of digits takes
precedence.
5.8 FIP CONTROLLER/DRIVER
An FIP controller/driver having the following features is provided:
(a) Automatic output of segment signals (DMA operation) and digit signals
by automatically reading display data
(b) Display mode registers (DSPM0 and DSPM1) that can control an FIP of 9 to 24 segments and 2 to 16 digits
(c) Port pins not used for FIP display can be used as output port or I/O port pins.
(d) Display mode register (DSPM1) can adjust luminance in eight steps.
(e) Hardware suitable for key scan application using segment pins
(f)
High-voltage output buffer (FIP driver) that can directly drive an FIP
(g) Display output pins can be connected to a pull-down resistor by the mask option.
