Found a bug (I think)

Check out the USART control info in the 16F628A errata document

You should be able to get control of the pins by clearing SPEN (RCSTA.7) and restoring the TRISB pin settings.

Also I recall a system variable called FLAGS or something similar that initialize the LCD module after the system has recovered from sleep mode.

I have tried clearing various bits of the registers (including specific serial port enable bits),
but not yet resetting the LCD.
It would be bad though since the LCD is updated every frame, and initialisation is a few commands.
I think maybe I’ll leave as is, and try to control and LED or such with the RB2 pin.
