How to connect VLCD pin when simulate LCD function?
In the current Sonix 8-bit 2 series products, SN8P2308 and SN8P2808 have LCD function,
the simulator is SN8ICE2K.
1. For SN8P2308, there are two LCD modules: R- type and C-type. For R- type, VLCD internal connected to VDD, outside need connected to ground through a 0.1uf capacitor. For C-type, VLCD pin should be connected to ground through 0.1uf/0.47uf.
2. For SN8P2808, when SEG24 ~ SEG31 pins for LCD applications, VLCD1 connected with VLCD; When for general IO pins applications, VLCD1 connected with VDD, VLCD pin is in idle state.
