9.1 Functions of 8-Bit Timer/Event Counters 50, 51
(1) Mode using 8-bit timer/event counters 50, 51 alone (discrete mode)
(2) Mode using cascade connection (16-bit resolution: cascade connection mode)
8-bit timer/event counters 50, 51 (TM50, TM51) have the following two modes.
<1> Interval timer
<2> External event counter
<3> Square-wave output
<4> PWM output
• Interval timer with 16-bit resolution
• External event counter with 16-bit resolution
• Square-wave output with 16-bit resolution
The timer operates as 8-bit timer/event counter 50 or 51.
It has the following functions.
The timer operates as a 16-bit timer/event counter by combining two 8-bit timer/event counters.
It has the following functions.
Figures 9-1 and 9-2 show block diagrams of 8-bit timer/event counters 50 and 51.
Interrupt requests are generated at the preset interval.
•
The number of pulses with high/low level widths of the signal input externally can be measured.
A square wave with an arbitrary frequency can be output.
•
A pulse with an arbitrary duty ratio can be output.
•
•
