Internal Peripheral Interface
UARTSerClk
Serial Clock used to provide an alternative clock to the
internally generated serial clock. Used in cases where the
allowable internally generated baud rates are not
satisfactory. This input can be individually connected to
either or both UART0 and UART1.

Signal Functional Description
(Part 4 of 6)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3k
to 3.3V, 10k
to 5V
)
3. Must pull down (recommended value is 1k
)
4. If not used, must pull up (recommended value is 3k
to 3.3V)
5. If not used, must pull down (recommended value is 1k
)
6. Strapping input during reset; pull-up or pull-down required
