U-TIMER (16-bit Timer for UART Baud Rate Generation)
The U-TIMER is a 16-bit timer for generating UART baud rate. Combination of chip operating frequency and
reload value of U-TIMER allows flexible setting of baud rate.
The U-TIMER operates as an interval timer by using interrupt issued on counter underflow.
The MB91107 has 3 channel U-TIMER embedded on the chip. An interval of up to 216
× φ can be counted.
