16-BIT TIMING OPERATIONS USING ST7262 OR ST7263B MCUs

– Using the OLVL2 bit, select the level to be applied to the OCMP1 pin after a successful com-

parison with OC2R register.

Step 4. Configure the CR2 register:

– Set the PWM bit.

– Select the timer clock (CC[1:0]).

2.2.2 Example

For example, to generate a PWM signal with the same characteristics as the example for the

ST7262 (see Section 2.1.1):

High Level period = 500 µs

Low Level period = 200 µs

PWM signal full period = 700 µs

So we can calculate the following values:

OC2R = 578h - 5h = 573h

OC1R = 3E8h - 5h = 3E3h

OLVL1 = 1 & OLVL2 = 0
