874 / 1350 page  Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2) MC9S12XDP512 Data Sheet, Rev. 2.17 874 Freescale Semiconductor 22.3.2.63 Port AD0 Data Direction Register 1 (DDR1AD0) Read: Anytime. Write: Anytime. This register configures pins PAD[07:00] as either input or output. 76543210 R DDR1AD07 DDR1AD06 DDR1AD05 DDR1AD04 DDR1AD03 DDR1AD02 DDR1AD01 DDR1AD00 W Reset 00000000 Figure 22-65. Port AD0 Data Direction Register 1 (DDR1AD0) Table 22-58. DDR1AD0 Field Descriptions Field Description 7–0 DDR1AD0[7:0] Data Direction Port AD0 Register 1 0 Associated pin is configured as input. 1 Associated pin is configured as output. Note: Due to internal synchronization circuits, it can take up to 2 bus clock cycles until the correct value is read on PTAD01 register, when changing the DDR1AD0 register. Note: To use the digital input function on port AD0 the ATD0 digital input enable register (ATD0DIEN) has to be set to logic level “1”. |
