7 / 67 page  HB288256/192/160/128/096/064/032C5 7 Signal name Direction Pin No. Description -IOWR (PC Card Memory mode) I 35 This signal is not used. -IOWR (PC Card I/O mode) -IOWR is used for control of data write in I/O task file area. This card does not respond to -IOWR until I/O card interface setting up. -IOWR (True IDE mode) -IOWR is used for control of data write in I/O task file area. This card does not respond to -IOWR until True IDE interface setting up. -OE (PC Card Memory mode) I 9 -OE is used for the control of reading register’s data in attribute area or task file area. -OE (PC Card I/O mode) -OE is used for the control of reading register’s data in attribute area. -ATASEL (True IDE mode) To enable True IDE mode this input should be grounded by the host. RDY/-BSY (PC Card Memory mode) O 37 The signal is RDY/-BSY pin. RDY/-BSY pin turns low level during the card internal initialization operation at VCC applied or reset applied, so next access to the card should be after the signal turned high level. -IREQ (PC Card I/O mode) This signal is active low -IREQ pin. The signal of low level indicates that the card is requesting software service to host, and high level indicates that the card is not requesting. INTRQ (True IDE mode) This signal is the active high Interrupt Request to the host. -REG (PC Card Memory mode) Attribute memory select I 44 -REG is used during memory cycles to distinguish between task file and attribute memory accesses. High for task file, Low for attribute memory is accessed. -REG (PC Card I/O mode) -REG is constantly low when task file or attribute memory is accessed. -REG (True IDE mode) This input signal is not used and should be connected to VCC. |
