    Default Setting PortB.7 as output on 16F627/8/48

    I'm having trouble getting PortB.1 to work as a digital output on a PIC16F648.
    I have pored over the documentation and tried all the registers - see below.
    What am I missing? I just need to blink an LED with this output and I'm committed to a PCB that locks me into this pin.

    TRISB = %00000000 ' set all as outputs
    CCP1CON = 0 ' turn off capture/compare mode (set all digital I/O)
    CMCON = 7 ' disable comparators
    OPTION_REG = %10000000 ' bit 7 = 1 disables weak pull-ups on portB
    INTCON = 0 ' disable interrupts

    What did I miss?
