Address/GPIO Enable Register (AGPIOEN) Bit Functions RESET BIT NO. BIT NAME FUNCTION VALUE Enable or disable GPIO function of Address Bus of EMIF. 15 −0 AIOENx 0 AIOENx = 0; GPIO function of Ax line is disabled; i.e., Ax has address function. AIOENx = 1; GPIO function of Ax line is enabled; i.e., Ax has GPIO function. Figure 3-10. Address/GPIO Direction Register (AGPIODIR) Bit Layout Table 3-10. Address/GPIO Direction Register (AGPIODIR) Bit Functions RESET BIT NO. BIT NAME FUNCTION VALUE Data direction bits that configure the Address Bus configured as I/O pins as either input or output pins. 15 −0 AIODIRx 0 AIODIRx = 0; Configure corresponding pin as an input. AIODIRx = 1; Configure corresponding pin as an output. Figure 3-11. Address/GPIO Data Register (AGPIODATA) Bit Layout Table 3-11. Address/GPIO Data Register (AGPIODATA) Bit Functions RESET BIT NO. BIT NAME FUNCTION VALUE Data bits that are used to control the level of the Address Bus configured as I/O output pins, and to monitor the level of the Address Bus configured as I/O input pins. If AIODIRn = 0, then: AIODx = 0; Corresponding I/O pin is read as a low. 15 −0 AIODx 0 AIODx = 1; Corresponding I/O pin is read as a high. If AIODIRn = 1, then: AIODx = 0; Set corresponding I/O pin to low. AIODx = 1; Set corresponding I/O pin to high.
