16 / 82 page  Electrical interface SMCxxxAF 16/82 Table 9. Signal description Signal name Direction Pin Description A10 to A0 (PC card memory mode) I 8,10,11,12, 14,15,16,17, 18,19,20 Used (with –REG) to select: the I/O Port Address registers, the memory mapped Port Address registers, a byte in the card's information structure and its Configuration Control and Status registers. A10 to A0 (PC card I/O mode) Same as PC card memory mode. A2 to A0 (True IDE mode) Only A2 to A0 are used to select the one of eight registers in the task file, the remaining lines should be grounded. BVD1 (PC card memory mode) I/O 46 The battery voltage status of the card, as no battery is required it is asserted High. –STSCHG (PC card I/O mode) Alerts the host to changes in the READY and Write Protect states. Its use is controlled by the Card Configuration and Status register. –PDIAG (True IDE mode) The Pass Diagnostic signal in the master/slave handshake protocol. BVD2 (PC card memory mode) I/O 45 The battery voltage status of the card, as no battery is required it is asserted High. –SPKR (PC card I/O mode) The binary audio output from the card. It is asserted High as audio functions are not supported. –DASP (True IDE mode) This input/output is the disk active/slave present signal in the master/slave handshake protocol. D15-D00 (PC card memory mode) I/O 31,30,29,28, 27,49,48,47, 6,5,4,3,2, 23,22,21 Carry the data, commands and status information between the host and the controller. D00 is the LSB of the even byte of the word. D08 is the LSB of the odd byte of the word. D15-D00 (PC card I/O mode) Same as PC card memory mode. D15-D00 (True IDE mode) All task file operations occur in byte mode on D00 to D07 while all data transfers are 16 bit using D00 to D15. GND (PC card memory mode) 1,50 Ground. GND (PC card I/O mode) Same for all modes. GND (True IDE mode) Same for all modes. –INPACK (PC card memory mode) O43 Not used, should not be connected to the host. –INPACK (PC card I/O mode) The Input Acknowledge is asserted when the Card is selected and responding to an I/O read cycle at the current address on the bus. It is used by the host to control the enable of any input data buffers between the Card and CPU. Reserved (True IDE mode) Not used, should not be connected to the host. |
