Supporting Multiple SD Devices with CoolRunner-II CPLDs Summary
... Host and SD Cards should be high impedance with a weak pull-up. Hence, the circuit in Figure 4 is designed to tristate the CoolRunner-II device’s output buffers, thereby allowing the external pull-up resistors to take effect. Register A (A_REG) and Register B (B_REG) are both designed to be initiali ...

Field-programmable gate array
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence ""field-programmable"". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). (Circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare.)FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects that allow the blocks to be ""wired together"", like many logic gates that can be inter-wired in different configurations. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR. In most FPGAs, logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of memory.
