PWC Timer (x 2, PWC0 is not present in MB90465 series)
The PWC (pulse width count) timer is a 16-bit multi-function up-counter with reload timer functions and input-
signal pulse-width count functions as well.
The PWC timer consists of a 16-bit counter, on input pulse divider, a divide ratio control register, a count input
pin, a pulse output pin, and a 16-bit control register.
The PWC timer has the following features :
Interrupt generated when timer overflow or end of PWC measurement.
EI2OS supported
Timer functions :
- Generates an interrupt request at set time intervals.
- Outputs pulse signals synchronized with the timer cycle.
- Selects the counter clock from among three internal clocks.
Pulse-width count functions
- Counts the time between external pulse input events.
- Selects the counter clock from among three internal clocks.
- Count mode
H pulse width (rising edge to falling edge) /L pulse width (falling edge to rising edge)
Rising-edge cycle (rising edge to falling edge) /Falling-edge cycle (falling edge to rising edge)
Count between edges (rising or falling edge to falling or rising edge)
Capable of counting cycles by dividing input pulses by 22, 24, 26, 28 using an 8-bit input divider.
Generates an interrupt request upon the completion of count operation.
Selects single or consecutive count operation.
