When this terminal is 0, an MMC/SD card is inserted in the socket. The PCI7x21/PCI7x11 controller debounces the MC_CD_0 signal such that instability of the signal does not cause false card insertions. The debounce time is approximately 50 ms. The MC_CD_0 signal is not debounced on card removals. The filtered MC_CD_0 signal is used in the MMC/SD card detection and power control logic. The MMC/SD card detection and power control logic contains three main states: • Socket empty, power off • Card inserted, power off • Card inserted, power on The PCI7x21/PCI7x11 controller detects a Memory Stick card insertion through the MC_CD_1 terminal. When this terminal is 0, a Memory Stick card is inserted in the socket. The PCI7x21/PCI7x11 controller debounces the MC_CD_1 signal such that instability of the signal does not cause false card insertions. The debounce time is approximately 50 ms. The MC_CD_1 signal is not debounced on card removals. The filtered MC_CD_1 signal is used in the Memory Stick card detection and power control logic.
