Hi!
I can't find the PSB-Pin to switch the LCD Module to an serial LCD-Module (SPI-Mode). Which Pin or Pad is the PSB?
datasheet:
...
function Description:
System interface
ST7920 supports 3 kinds of bus interface to MPU. 8 bits parallel, 4 bits parallel and clock
synchronized serial interface. Parallel interface is selected by PSB="I" and serial interface by
PSB="0". 8 bit / 4 bit interface is selected by function set instruction DL bit.
