Bit 25—Control Input Pin Pull-Up Resistor Control (IPUP): Specifies the pull-up resistor
status for control input pins (NMI, ,5/3–,5/6, %5(4, MD6/,2,649, 5'<). IPUP is initialized
by a power-on reset.

Bit 24—Control Output Pin Pull-Up Resistor Control (OPUP): Specifies the pull-up resistor
status for control output pins (A[25:0], %6, &6Q, 5', :(Q, RD/:5, 5$6, 5$65, &(5$, &(5%,
5'5, RD/:55) when high-impedance. OPUP is initialized by a power-on reset.
