3rd board for NEDONAND project
It’s stackable 4-bit part of NEDONAND program counter with parallel load that uses 2 board NEDONAND-2 to count from 0000 to 1111 binary. Pins description (2 rows - male for inputs and female for outputs):
1.1) IN (OUT) - count enable
1.2) ACT0 - external writing signal "0"
1.3) ACT1 - external writing signal "1"
1.4) /RESET - master reset
1.5) CLK - clock signal
1.6) NC - not connected
1.7) VCC - power +5V
1.8) GND - ground
2.1) D0 - bit 0 for writing
2.2) D1 - bit 1 for writing
2.3) D2 - bit 2 for writing
2.4) D3 - bit 3 for writing
2.5) D4 - used in next stacked boards
2.6) D5 - used in next stacked boards
2.7) D6 - used in next stacked boards
2.8) D7 - used in next stacked boards
2.9) D8 - used in next stacked boards
2.10) D9 - used in next stacked boards
2.11) D10 - used in next stacked boards
2.12) D11 - used in next stacked boards (in case of 2K memory it's "0")
4-bit address output header on the right:
3.1) A0
3.2) A1
