• Manufacturer: ETC2 [List of Unclassifed Manufacturers]

1.2.2 Parallel I/O
The primary means of communication between the base board and the mezzanine is through the parallel
I/O interface. This group of signals consists of PIO_D[0-15], PIO_A[0-21], PIO_CS-, MODID[0-3],
PIO_WAIT-, PIO_RD-, PIO_WR-, PRCLK, PIO_IRQ0-.
1.2.2.1 MODID
Each mezzanine in an EmPack system has a unique Module ID (MODID) at any given time. The
MODID signals on the bottom connector of the first mezzanine (closest to the base board) are controlled
directly by the base board. The MODIDs of two adjacent mezzanines have the following relationship:
