/*
    A note about clock multipliers and dividers:

    E1-16[T] and E1-32[T] accept a straight clock

    E1-16X[T|N] and E1-32X[T|N] accept a clock and multiply it
        internally by 4; in the emulator, you MUST specify 4 * XTAL
        to achieve the correct speed

    E1-16XS[R] and E1-32XS[R] accept a clock and multiply it
        internally by 8; in the emulator, you MUST specify 8 * XTAL
        to achieve the correct speed
