13. Input capture

• 4 channels

14. Other interval timers

• 16-bit timer : 3 channels (U-TIMER)

• PPG timer : 4 channels

• Watchdog timer : 1 channel

15. Other features

• Reset resources : watchdog timer/software reset/external reset (INIT pin)

• Power-saving modes : Stop mode, sleep mode

• Clock control

Gear function : Allows arbitrary different operating clock frequencies to be set for the CPU and peripherals.

You can select one of the 16 gear clock factors of 1/1 to 1/16. PLL multiplication can also be selected. Note,

however, that peripherals operate at a maximum of 34 MHz.

• CMOS technology : 0.25

µm

• Power supply (analog power supply): 3.3 V

± 0.3 V (internal regulator used)

■ PRODUCT LINEUP

*1 : The Fujitsu product of real time OS REALOS/FR by conforming to the

µITRON 3.0 is stored and optimized

with the MB91302A.

*2 : The ROM stores the IPL (Internal Program Loader) . Loading various programs can be executed from the

external system by the internal UART/SIO. Using this function, for example, writing on board to the Flash

memory connected to the external can be executed.
