48 / 134 page  Chapter 6 Parallel Input/Output Control SC9RS08KA2 Series Data Sheet, Rev. 1 48 Freescale Semiconductor corresponding pulling device enable register bit. The pulling device is also disabled if the pin is controlled by an analog function. 6.3.1.2 Pullup/Pulldown Control Pullup/pulldown control is used to select the pullup or pulldown device enabled by the corresponding PTAPE bit. Figure 6-5. Pullup/Pulldown Device Control for Port A (PTAPUD) 6.3.1.3 Output Slew Rate Control Enable Slew rate control can be enabled for each port pin by setting the corresponding bit in the slew rate control register (PTASEn). When enabled, slew control limits the rate at which an output can transition in order to reduce EMC emissions. Slew rate control has no effect on pins that are configured as inputs. 76 54 321 0 R 00 PTAPE5 PTAPE4 0 PTAPE2 PTAPE1 PTAPE0 W Reset: 000 00 000 Figure 6-4. Internal Pulling Device Enable for Port A Register (PTAPE) Table 6-3. PTAPE Register Field Descriptions Field Description 5:4,2:0 PTAPE[5:4,2:0] Internal Pulling Device Enable for Port A Bits — Each of these control bits determines whether the internal pulling device is enabled for the associated PTA pin. For port A pins that are configured as outputs, these bits have no effect and the internal pullup devices are disabled. 0 Internal pulling device disabled for port A bit n. 1 Internal pulling device enabled for port A bit n. 76 54 321 0 R 00 PTAPUD5 PTAPUD4 0 PTAPUD2 PTAPUD1 PTAPUD0 W Reset: 000 00 000 Table 6-4. PTAPUD Register Field Descriptions Field Description 5:4,2:0 PTAPUD[5:4,2:0] Pullup/Pulldown Device Control for Port A Bits — Each of these control bits determines whether the internal pullup or pulldown device is selected for the associated PTA pin. The actual pullup/pulldown device is only enabled by enabling the associated PTAPE bit. 0 Internal pullup device is selected for port A bit n. 1 Internal pulldown device is selected for port A bit n. |
