Figure 14-26 shows a signal configuration for a UART1/CODEC interface.
Figure 14-27 shows a signal configuration for a UART1/CODEC interface. An MCF5407
general-purpose I/O (GPIO) is used as a reset to the AC ‘97 device.
14.5 Operation
This section describes operation of the clock source generator, transmitter, and receiver.
14.5.1 Transmitter/Receiver Clock Source
CLKIN serves as the basic timing reference for the clock source generator logic, which
consists of a clock generator and a programmable 16-bit divider dedicated to the UART.
The clock generator cannot produce standard baud rates if CLKIN is used, so the 16-bit
divider should be used.
