NO. | NAME | ||
A1 | DAT2A | I/O | Data bit 2 connected to host. Referenced to VCCA. Includes a 40-kΩ pullup resistor to VCCA. |
A2 | VCCA | Pwr | A-port supply voltage. VCCA powers all A-port I/Os and control inputs. |
A3 | WP | O | Connected to write protect on the mechanical connector. The WP pin has an internal 100-kΩ (± 30%) pullup resistor to VCCA. Leave unconnected if not used. |
A4 | DAT2B | I/O | Data bit 2 connected to memory card. Referenced to VCCB. Includes a 40-kΩ pullup resistor to VCCB. |
B1 | DAT3A | I/O | Data bit 3 connected to host. Referenced to VCCA. Includes a 40-kΩ pullup resistor to VCCA. |
B2 | CD | O | Connected to card detect on the mechanical connector. The CD pin has an internal 100-kΩ (± 30%) pullup resistor to VCCA. Leave unconnected if not used. |
B3 | VCCB | Pwr | B-port supply voltage. VCCB powers all B-port I/Os. |
B4 | DAT3B | I/O | Data bit 3 connected to memory card. Referenced to VCCB. Includes a 40-kΩ pullup resistor to VCCB. |
C1 | CMDA | I/O | Command bit connected to host. Referenced to VCCA. Includes a 40-kΩ pullup resistor to VCCA. |
