CPCB950000005A Interface Card

This interface card is used in conjunction with the CICE950000005A

Switch S1 is used to simulate a low voltage condition, a situation which can be detected internally by the HT95C400, HT95C300, HT95C200, HT95L400/40P, HT95L300/30P, HT95L200/20P and HT95L100/10P devices. When switch S1 is pressed, the low battery flag (LBFG; bit 4 of LCDC register) will be set, resulting in a simulated low battery condition. For the J5 and J6 connectors, as the devices in the 95 series have different package types, the common pads are also different. The table below provides the necessary details.

Description: On the interface card, for the LCD, no actual signal pins are provided as the LCD is fully simulated by the IDE300 software. For the LCD common I/O pins, this is controlled by the related bits in the LCDIO register, for more details consult the HT95 datasheet.
