16-bit reload timer (x 2)
The 16-bit reload timer provides two operating mode, internal clock mode and event count mode. In each
operating mode, the 16-bit down counter can be reloaded (reload mode) or stopped by underflow (one-shot
mode).
Output pins TO1 and TO0 are able to output different waveform according to the counter operating mode. TO1
and TO0 toggles when counter underflows if counter is operated as reload mode. TO1 and TO0 output specified
level (H or L) during counting if the counter is in one-shot mode.
Features of the 16-bit reload timer :
Interrupt when timer underflows
Supports for EI2OS
Internal clock operating mode :
Three internal count clocks can be selected.
Counter can be activated by software or external trigger (signal at TIN1 and TIN0 pins).
Counter can be reloaded or stopped when underflow after activated.
Event count operating mode :
Counter counts down one by one with specified edge at TIN1 and TIN0 pins.
Counter can be reloaded or stopped when underflow.
(1) Register configuration
Note : Registers TMR0, TMR1/TMRD0, TMRD1 are word access only.
