XR16M698 REGISTERS
The XR16M698 octal UART register set consists of the Device Configuration Registers that are accessible
directly from the data bus for programming general operating conditions of the UARTs and monitoring the
status of various functions. These functions include all 8 channel UART’s interrupt control and status, 16-bit
general purpose timer control and status, sleep mode, soft-reset, and device identification and revision. Also,
each UART channel has its own set of internal UART Configuration Registers for its own operation control,
status reporting and data transfer. These registers are mapped into a 256-byte of the data memory address
space. The following paragraphs describe all the registers in detail.
