FUNCTIONAL DESCRIPTION
The MSM60804 offers PC card interface which is functionally compatible to the Intel SE82365SL.
The MSM60804 supports the ISA on its system interface side and function to control 2 slots of the
PCMCIA2.1 or JEIDA.2 on its card interface side. For details of pins and registers, see “5.Pin
Description‘‘ and “7. Register Description.‘‘
Power Control
The MSM60804 supplies 5V or 3V power to the PCIC core and to the interface buffer on the system
side.
This power is supplied through the VCCISA and VCCCORE pins.
The VCCISA voltage must be equal to the VCCCORE voltage.
The interface buffer on the system side supports 5V or 3V CMOS and 5V or 3V TTL interface levels.
The levels are selected by the ISAPWR signal.
Power supply voltage to the interface buffer on the card side is selected to each slot from either 5V
or 3V according to the rated voltage of the PC card inserted into each slot.
Power is supplied to the interface buffer on the card side through the VCCA and VCCB pins.
Voltages supplied to VCCA and VCCB and voltages supplied to slots are determined by
controlling the external power supply circuit by VCCEN0 and VCCEN1.
The VCCEV0 and VCCEN1 outputs are determined by the voltage control registers (+17h and
+57h).
The voltage of VPP power supplied to card slots are determined by controlling the external supply
by the V10 and V11 pins.
The V10 and V11 outputs are determined by the power control registers (+02h and +42h).
Memory Access
The memory address space of the PC card supports both attribute memory and common memory
(maximum 64M bytes each).
Attribute memory or common memory is selected by the REG signal.
The REG signal output is determined by the following two registers:
Interrupt and General-Purpose Register (+03h or +43h)
Card Memory Offset Address # High Byte Register
Accessing to the memory space of the PC card is made through the Memory Address Mapping
window.
The Memory Address Mapping window allocates the following three addresses as shown below.
System memory mapping start address.
System memory mapping offset address
Card memory offset address
