CPU No Access Output Enable
Normal: write once

Special: write anytime
1 The associated pin (port E, bit 7) is general-purpose I/O.
0 The associated pin (port E, bit 7) is output and indicates whether the cycle is a CPU free cycle.
This bit has no effect in single-chip or special peripheral modes.
Pipe Status Signal Output Enable
Normal: write once
Emulation: write never
Special: write anytime.
0 The associated pins (port E, bits 6:5) are general-purpose I/O.
1 The associated pins (port E, bits 6:5) are outputs and indicate the state of the instruction queue
This bit has no effect in single-chip or special peripheral modes.
No External E Clock
Normal and special: write anytime
Emulation: write never
0 The associated pin (port E, bit 4) is the external E clock pin. External E clock is free-running if ESTR = 0
1 The associated pin (port E, bit 4) is a general-purpose I/O pin.
External E clock is available as an output in all modes.
Low Strobe (LSTRB) Enable
Normal: write once
Emulation: write never
Special: write anytime.
0 The associated pin (port E, bit 3) is a general-purpose I/O pin.
1 The associated pin (port E, bit 3) is configured as the LSTRB bus control output. If BDM tagging is enabled,
This bit has no effect in single-chip, peripheral, or normal expanded narrow modes.
Note: LSTRB is used during external writes. After reset in normal expanded mode, LSTRB is disabled to provide
