ST92185B - PWM GENERATOR

PWM GENERATOR (Cont’d)

OUTPUT COMPLEMENT REGISTER (OCPL)

R251- Read/Write

Reset Value: 0000 0000 (00h)

This register allows the PWM output level to be

complemented on an individual bit basis.

In default mode (reset configuration), each com-

parison true between a Compare register and the

counter has the effect of setting the corresponding

output.

At counter clear (either by autoclear comparison

true, software clear or overflow when in free run-

ning mode), all the outputs are cleared.

By setting each individual bit (OCPL.x) in this reg-

ister, the logic value of the corresponding output

will be inverted (i.e. reset on comparison true and

set on counter clear).

Example: When set to “1”, the OCPL.1 bit comple-

ments the PWM output 1.

Bit 7 = OCPL.7:

Complement PWM Output 7.

Bit 6 = OCPL.6:

Complement PWM Output 6.

Bit 5 = OCPL.5:

Complement PWM Output 5.

Bit 4 = OCPL.4:

Complement PWM Output 4.

Bit 3 = OCPL.3:

Complement PWM Output 3.

Bit 2 = OCPL.2:

Complement PWM Output 2.

Bit 1 = OCPL.1:

Complement PWM Output 1.

Bit 0 = OCPL.0:

Complement PWM Output 0.

OUTPUT ENABLE REGISTER (OER)

R252 - Read/Write

Reset Value: 0000 0000 (00h)

These bits are set and cleared by software.

0: Force the corresponding PWM output to logic

level 1. This allows the port pins to be used for

normal I/O functions or other alternate functions

(if available).

1: Enable the corresponding PWM output.

Example: Writing 03h into the OE Register will en-

able only PWM outputs 0 and 1, while outputs 2, 3,

4, 5, 6 and 7 will be forced to logic level “1”.

Bit 7 = OE.7:

Output Enable PWM Output 7.

Bit 6 = OE.6:

Output Enable PWM Output 6.

Bit 5 = OE.5:

Output Enable PWM Output 5.

Bit 4 = OE.4:

Output Enable PWM Output 4.

Bit 3 = OE.3:

Output Enable PWM Output 3.

Bit 2 = OE.2:

Output Enable PWM Output 2.

Bit 1 = OE.1:

Output Enable PWM Output 1.

Bit 0 = OE.0:

Output Enable PWM Output 0.
