Description
Pin No.
VD0 to VD15
I/O
68 to 78,
68 to 83
These pins are interfaced with the VRAM data bus.
81 to 85
For a 16-bit MPU configuration, VD0 to VD7 must be
connected to even addresses, and VD8 to VD15 to
odd addresses. For an 8-bit configuration, VD8 to
VD15 must be connected to VDD.
VA0 to VA12
