Internal clock mode
The 16-bit reload timer has the following functions:
• Count clock is selectable among 3 internal clocks and external event clock.
• Activation trigger is selectable between software trigger and external trigger.
• Generation of CPU interrupt is allowed upon occurrence of underflow on 16-bit timer register. Available as an
• When underflow of 16-bit timer register (TMR) occurs, one of two reload modes is selectable between one-

• MB90385 series device has 2 channels of built-in 16-bit reload timer.
• The 16-bit reload timer is set to internal clock mode, by setting count clock selection bit (TMCSR: CSL1, CSL0)
• In the internal clock mode, the counter decrements in synchronization with the internal clock.
• Three types of count clock cycles are selectable by count clock selection bit (TMCSR: CSL1, CSL0) in timer
• Edge detection of software trigger or external trigger is specified as an activation trigger.
