    Preliminary
    5.6.2.1
    Reserved—Bits 15–6
    This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
    5.6.2.2
    EOnCE Receive Register Full Interrupt Priority Level
    (RX_REG IPL)—Bits 5–4
    This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 1 through 3.
    It is disabled by default.
    00 = IRQ disabled (default)
    01 = IRQ is priority level 1
    10 = IRQ is priority level 2
    11 = IRQ is priority level 3
    5.6.2.3
    EOnCE Transmit Register Empty Interrupt Priority Level
    (TX_REG IPL)—Bits 3–2
    This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 1 through 3.
    It is disabled by default.
    00 = IRQ disabled (default)
    01 = IRQ is priority level 1
    10 = IRQ is priority level 2
    11 = IRQ is priority level 3
    5.6.2.4
    EOnCE Trace Buffer Interrupt Priority Level (TRBUF IPL)—
    Bits 1–0
    This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 1 through 3.
    It is disabled by default.
    00 = IRQ disabled (default)
    01 = IRQ is priority level 1
    10 = IRQ is priority level 2
    11 = IRQ is priority level 3
