PIC16F1779: PWMx vs. PWMxOUT in header?

[apakSeO]

CCS v5.080
PIC16F1779

In the 16F1779.h header file, the #pin_select section contains entries for PWMxOUT as well as PWMx. For example, PWM3 is a PPS function, as well as PWM3OUT, in the header.

What is the difference between using #pin_select with PWMx vs. PWMxOUT? Is there any difference between the two? If I'm supposed to "just know" what the difference in these two is supposed to be, how would I have obtained this knowledge on my own?

The only reference to this in the data sheet is that PWM3 is the source peripheral, and PWM3OUT is the output pin. I can't find any reference to this disparity in the compiler manual either; the header file does not explain the usage scenarios of one vs. the other.

Generally, the names you should use are those in the pin selection table in the data sheet.

PWMxOUT.

However in this particular case CCS opted to provide an alternative name that might seem simpler. So just PWMx. Either is legitimate and does the same.
