UART Peripheral Interface
The UART interface can be configured as follows:
1. One 8-pin, where n = 0
2. Two 4-pin, where n = 0 & 1
3. One 4-pin, where n = 0 and two 2-pin, where n = 1 & 2
4. Four 2-pin, where n = 0 & 1 & 2 & 3

Signal Name
Receive data.
Bus Request. Used when the PPC440EPx needs to regain
control of peripheral interface from an external master.
External Acknowledgement. Used by the PPC440EPx to indicate
that a data transfer occurred.
External Request. Used by an external master to indicate it is
prepared to transfer data.
Peripheral Reset. Used by an external master and by
synchronous peripheral slaves.
Note: The state of signals or clocks cannot be guaranteed until
the ExtReset signal has been de-asserted.
Hold Acknowledge. Used by the PPC440EPx to transfer
ownership of peripheral bus to an external master.
Hold Request. Used by an external master to request ownership
of the peripheral bus.
Hold Primary. Used by an external master to indicate the priority
of a given external master tenure.
Peripheral Clock. Used by an external master and by
synchronous peripheral slaves.
The SerClk input provides an alternative to the internally
generated serial clock. It is used in cases where the allowable
internally generated clock rates are not satisfactory.
Transmit data.
Data Carrier Detect.
