+NES Gamepad signalling
+-------------------------------------------------------------------------------
+
+Synthetically generated NES gamepad signalling.
+
+SPI settings are always:
+
+Clock polarity = 1
+Clock phase    = 0
+Bit order      = msb-first
+Word size      = 8
+
+Chip-select is not used and must not be assigned to any channel.

+
+VCC   - Power 5V
+GND   - Ground
+CUP   - Shift register clock (CLK)
+OUT 0 - Shift register latch (optional)
+D1    - Gamepad data (MISO)
+D3    - Data (unused)
+D4    - Data (unused)
+
+Data pins D3 and D4 are not used by the standard game pad but by special
+controllers like the Nintento Zapper light gun.
