// Link seam for testing the real via.c.

//

// via.c holds two 65C22s. The generic half -- the registers, the interrupt

// flags and enables, the timers and the shift register -- is shared by both

// and touches nothing outside the chip. The other half wires VIA 1's ports to

// the machine: I2C to the SMC and RTC, the IEC serial bus, and the NES

// controllers.

//

// VIA 2 is the user port and via2_read()/via2_write() pass straight through to

// the generic half, so a test of the chip itself drives VIA 2 and needs none

// of that. This supplies what VIA 1's half refers to so the translation unit

// links.

//

// Every port here is inert and reads as an idle bus. Nothing records: a test

// that depends on one of these has left the 65C22 and gone into the machine

// around it, and wants rewriting rather than accommodating.
