MB90246A Series
5. 16-bit Re-load Timer
The 16-bit re-load timer has an internal clock mode for counting down in synchronization to three types of internal
clocks and an event count mode for counting down detecting a given edge of the pulse input to the external bus
pin, and either of the two functions can be selectively used.
For this timer, an “underflow” is defined as the timing of transition from the counter value of “0000
H
” to “FFFF
H
”.
According to this definition, an underflow occurs after [re-load register setting value + 1] counts.
In operating the counter, the re-load mode for repeating counting operation after re-loading a counter value after
an underflow or the one-shot mode for stopping the counting operation after an underflow can be selectively used.
Because the timer can generate an interrupt upon an underflow, the timer conforms to the extended intelligent
I/O service (EI
2
OS).
The MB90246A series has 3 channels of 16-bit re-load timers.
