Hello all,
I have a CPU board which has a M16C/62P microcontroller and the microcontrollers three CS pins are connected to SRAM, EEPROM and ADC. Now I need to add LCD to the CPU board throuch the latch and I will need one more CS pin to the latch.
I am thinking to expand one of the microcontrollers CS pin to get two CS pins using address decoder in a way that this microcontrollers CS pin comes to the address decoder and based on address it selects one of the two CS pins.
Is there other possibilities mayby to expand CS pins?
