DESCRIPTION:
    Some commands of eccet manipulate bitfields.
    Where this is the case, you can employ bitop commands.
    If the data field starts with
    | the following value will be ORed to the current value
    & the following value will be ANDed with the current value
    ^ the following value will be XORed with the current value
    = or none of the above, the current value is replaced.
    If a tilde (~) follows the initial mode selector, the value
    is inverted before the operation takes place

EXAMPLES:
    23 or =0x17 - sets the value to 0b00010111
    |0x10   - ORs  the current value with 00010000 (sets bit 4)
    &~0x04  - ANDs the current value with 11111011 (clears bit 2)
