PWM assignment

Kazuma_Sasaki — Tue, 19 Mar 2019 11:57:39 GMT

i.MX8QXP is supporting 4x PWM channels according to description from "Table 1. i.MX 8QuadXPlus/8DualXPlus advanced features in IMX8QXPAEC Rev.0".

When I search PWM pins by Pins tool v5.0, seven pins appeared such as below figure.

It means that PWM0 is able to use only exclusively.

Ex : In case of MIPI_DSI0 is assignment to PWM0, ADMA_LCDIF, LSIO_PWM0 and MIPI_DSI1 can not use PWM0.

Is my understanding correct?

Best Regards,

Kazuma Sasaki.

Hello,

i.MX8QX supports following (separate) PWM channels:

1) 4 general purpose PWMs (in the Low Speed I/O (LSIO));

2) each of two MIPI DSI systems has own PWM to control the remote displays;

3) PWM of the ADMA, intended for the LCDIF.

Have a great day,
Yuri
