U-TIMER Registers

This section describes the configuration and functions of the registers used by the U-
TIMER.
■ U-TIMER Registers
Figure 8.2-1 shows the registers used by the U-TIMER.

■ U-TIMER (UTIM:UTIM2 to UTIM0)
Figure 8.2-2 shows the bit configuration of the U-TIMER (UTIM:UTIM2 to UTIM0).

ch.0 Address: 000064
ch.1 Address: 00006C
ch.2 Address: 000074
UTIM indicates the timer value. Use a 16-bit transfer instruction to access this register.
■ Reload Register (UTIMR:UTIMR2 to UTIMR0)
Figure 8.2-3 shows the bit configuration of the reload register (UTIMR:UTIMR2 to UTIMR0).

ch.0 Address: 000064
ch.1 Address: 00006C
ch.2 Address: 000074
UTIMR is a register that stores the value to be reloaded into UTIM if UTIM underflows.
Use a 16-bit transfer instruction to access this register.
Note:
When U-TIMER is used as a baud rate in UART mode 2 (CLK synchronous mode), setting "0" to
UTIMR is prohibited.
