PCIC Register Access
The MSM60804 provides a 40h register space for each slot.
The register address of slot A is 3Fh and the register address of slot B is 40h to 7Fh.
When two MSM60804 chips are cascaded, register addresses are decoded according to the status
of the SEL0 signal. Register addresses of slot C and slot D are respectively 80h to BFh and C0h to
FFh.

Accessing to the register address space is indirect addressing through I/O addresses of 3E0h and
3E1h.
The I/O address 3E0h specifies the register address to be accessed.
The I/O address 3E1h accesses a register specified by 3E0h.
Selection of Memory Mode or I/O Mode
The Memory PC Card Access Mode and the I/O PC Card Access mode are switched by register
setting.
A PC card access mode is selected by the following register:
Interrupt & General Control Register (+03h and +43h)
Functions of a specific pin of the PCMCIA are switched by mode switching.
Detection of Card Interface Status
TheMSM60804detectsthefollowingsevenPCcardstatusesandreflectsthemuponregistervalues:
The seven states are as follows:
Card detection (CD1 or CD2)
Card Power Supply Active (V10 or V11)
Voltage Sense (VSS0 or VSS1)
Ready/Busy (RDY) (for memory cards only)
Write Protect (WP) (for memory cards only)
Battery Voltage Detect (BV1 or BV2) (for memory cards only)
Status Change (BV1) (for I/O mode only)
The detected state is reflected upon the following two registers:
Interface Status register (+02h and +42h)
Voltage Control register (+17h and +57h)
