The Event Force register is a phantom register. These bits are merely control bits. They are not registered
and need no clearing. They provide software the ability to force various status and event bits in the
CL-PD6833. This gives software the ability to test and restore status. Writing ‘1’ to a bit in this register sets
the corresponding bit in the Status Event register and/or the Present State register. Bits 3:0 generate
Management Interrupt if the correct Mask bit is set.
Bit 0 — CSTSCHG/WAKEUP
This bit sets the Card Status Change bit in the Status Event register. The Present State register
remains unchanged.
Bit 1 — CCD1 Changed
This bit sets the CCD1 bit in the Status Event register. The Present State register remains
unchanged.
Bit 2 — CCD2 Changed
This bit sets the CCD2 bit in the Status Event register. The Present State register remains
unchanged.
Bit 3 — Power Cycle
This bit sets the Power Cycle bit in the Status Event register. The Present State register remains
unchanged.
Bit 4 — 16-Bit PC Card
This bit sets the 16-bit PC Card bit in the Present State register. If a card is installed in the socket,
writes to this bit are ignored.
