Updating HPWM frequently, safe?

[Christopher4187]

Old thread but very relevant to my issue.

Can I use HPWM10:

1. On an 18F87J50?
2. And have it glitch free?
3. To make a pulse train that's 140mS long and have varying duty cycles within the pulse train?

In other words: 300uS on, 200uS off, 300uS on on, 200uS off, 130uS on, 370 uS off, 300uS on, 200uS off, 130uS on, 370uS off, 170uS on, 330uS off, 130uS on, 370uS off, etc.

Each bit is 500uS and I don't need to modify anything while the packet is being sent; I can modify right before the next one is sent.
