Miscellaneous Control
The MISC register includes two bits for manually toggling the MPC8560 I
2
C bus. This regis-
ter can force which one of two SCC1 serial port sources are used for communication. One
port includes the front panel serial I/O, connector P14, or the DMC; the other port is con-
nector P13 serial I/O. P13 serial I/O is only enabled when the CT Bus Status register bit CTEN
(read only) is a 1. Alternatively, instead of forcing the front panel versus the P13 choice, the
hardware can be enabled to combine the received data from both ports
Register 8-13:
Miscellaneous Control (MISC), 0x34
REFCLK:
REFCLK control selects whether the FCC REFCLK is received from the baseboard and subse-
quently driven to the MPC8560, or if the FCC REFCLK is sourced by the CPLD as a 50 MHz
output and also driven to the MPC8560.
0 REFCLK input (default)
1 REFCLK output
