16-bit Reload Timer
The functions of the 16-bit reload timer are as follows :
Choose one of three internal clocks or an external event clock as the count clock.
Choose a software or external launch trigger.
An interrupt can be sent to the CPU in response to an underflow generated by the 16-bit timer register. Interrupts
can be used to utilize the timer as an interval timer.
When an underflow is generated by the 16-bit timer register (TMR) , select one-shot mode, where TMR counter
operation is halted, or reload mode, where the 16-bit reload register value is reloaded, and TMR count operation
continues.
Supports extended intelligent I/O service (EI2OS) .
The MB90495G Series features two on-chip 16-bit reload timer channels.
16-bit Reload Timer Operation Mode
Internal Clock Mode
Set the count clock selection bits of the timer control status register (TMCSR : CSL1, CSL0) to “00B”, “01B” or
“10B” to set the 16-bit reload timer to internal clock mode.
In internal clock mode, the timer counts down in synchronization with the internal clock.
Set the count clock selection bits of the timer control status register (TMCSR : CSL1, CSL0) to select one of
three count clock intervals.
Select software-triggered or externally triggered (edge detection) launch.
