XR16L788
HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART
The XR16L788 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.
The device configuration registers are directly accessible from the bus. This provides easy programming of
general operating parameters to the 788 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

status, 16-bit general purpose timer control and status, 8X or 16X sampling clock, sleep mode control, soft-
reset control, simultaneous UART initialization, and device identification and revision.
