Reset Control
The MSM60804 is reset by the RSTD signal from the system.
It is possible to read only the Configuration register when the PC card is removed by setting it on
the register.
Resetting of the Configuration register is enabled by the following register:
Card Detection & General Control Register (+16h and +56h)
For configuration registers, see the configuration register list.
The PC card in each slot can be reset individually by register setting.
Set the following register to reset the PC card:
Interrupt & General Control Register (+03h and +43h)
Interrupt Control
The MSM60804 supports interrupts by the IREQ signals from PC cards and interrupts due to card
status changed.
These interrupts can be assigned to each slot.
The interrupt by the IREQ signal can be assigned to one of the IRQ pins.
This assignment is set by the following register:
Interrupt & General Control Register (+03 and +43h)
The interrupt due to card status changed can be assigned to one of the IRQ numbers or to ICHK.
This assignment is set by the following register:
Interrupt & General Control Register (+03h and +43h)
Card status Change Interrupt Configuration Register (+05h and +45h)
Edge triggering or level triggering can be selected.
This selection is set by the following register:
General Control register (+1Eh ad +5Eh)
Power-Down Control
The MSM60804 supports the Power-Down mode. This mode can be set for each slot.
The Power-Down mode can be set by the following register:
Voltage Control register (+17h and +57h)
Cascade Connection
By internal decoding of register address, it is possible to connect two MSM60804 chips in a cascade
manner and to support four slots simultaneously.
When the base address is set by the SPKR or SEL0 input, the register address of the second
MSM60804 is assigned to 80h to FFh.
