As more NSEs are added to the DQ bus, the capacitive load
on the bus increases, reducing the bus speed. CYNSE80192
gets around this by using external transceivers, and provides
a glueless support to add the transceivers (Phillips
74ALVT16652)
CYNPC80192 (see Figure 14-1).
The XVER_0, XVER_1, and XVER_2 are electrically buffered
versions of the same logical signal in the CYNPC80192
device. The XVER_0_L, XVER_1_L, and XVER_2_L are also
electrically buffered versions of the same logical signal in the
CYNPC80192 device. Multiple copies of these signals are
