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 register 0-2 (DSPM0-DSPM2) that can control an FIP of 9 to 40 segments and 2 to 16 digits
(c) The output timing of the digit signal can be freely set by selecting the display mode 2 by using the display mode
register 0 (DSPM0).
(d) Port pins not used for FIP display can be used as output port or I/O port pins (however, FIP0-FIP12 are display
output pins).
(e) Display mode register 1 (DSPM1) can adjust luminance in eight steps.
(f) Hardware suitable for key scan application using segment pins
(g) High-voltage output buffer (FIP driver) that can directly drive an FIP
(h) Display output pins can be connected to a pull-down resistor by mask option.
