XR16M698
1.62V TO 3.63V HIGH PERFORMANCE OCTAL UART WITH 32-BYTE FIFO
The device configuration registers are directly accessible from the bus. This provides easy programming of
general operating parameters to the 698 UART and for monitoring the status of various functions. The device
configuration registers are mapped onto address 0x80-8F as shown on the register map in
