The CXC ports SER1, SER2 and SER3 are equivalent to ports SCC2, SCC3 and SCC4 resp. on the
68xx360.
With regard to special CXC capabilities, the CXC pinout on the VM162/VM172 has been developed to
provide maximum compatibility between the standard CXC functions. In addition, all signals are availa-
ble in order to configure 2 time division multiplexed channels via the CXC (ISDN, PCM, GCI and so
on). Multi-function pins with incompatible functions with regard to the 68302 and 68EN360 (called
user defined in the generic CXC specification) are not part of the VM162/VM172 CXC specification.
Although the SMCs are configured on the base board, these ports are also integrated on the CXC. This
is because of possible ISDN applications where SMCs can be integrated and other protocols supported
by the 68EN360.
Note: If the RCLK2 signal (CXM pin c16) is required, jumper J11 (24 MHz clock) must be opened and
the serial drivers delivered by PEP modified.
