I/O Lines
Debug operation
Power Manager
Interrupts
The pins used for interfacing the PWM may be multiplexed with I/O controller lines. The pro-
grammer must first program the I/O controller to assign the desired PWM pins to their peripheral
function. If I/O lines of the PWM are not used by the application, they can be used for other pur-
poses by the I/O controller.
Not all PWM outputs may be enabled. If an application requires only four channels, then only
four I/O lines will be assigned to PWM outputs.
The PWM clock is running during debug operation.
The PWM clock is generated by the Power Manager. Before using the PWM, the user must
ensure that the PWM clock is enabled in the Power Manager. However, if the application does
not require PWM operations, the PWM clock can be stopped when not needed and be restarted
later. In this case, the PWM will resume its operations where it left off.
In the PWM description, CLK_PWM is the clock of the peripheral bus to which the PWM is
connected.
The PWM interrupt line is connected to the interrupt controller. Using the PWM interrupt requires
the interrupt controller to be programmed first.
