Interrupts
For interrupt execution, the specific
register must be set including the
PWMCTLx
on the programmable interrupt to be used.
Whenever a period starts, the PWM interrupt is generated. Since all four
PWM units share the same interrupt vector, the interrupt service routine
should read the
interrupt. Next, the ISR clears the status bits of the
explicitly writing 1.
Debug Features
The module contains four debug status registers (
be used for debug aid. Each register is available per unit. The registers
return current status information about the AH, AL, BH, BL output pins.
Programming Example
Listing 10-1
shows the four steps used to configure a PWM module.
