PD6710/’22 — ISA-to-PC-Card (PCMCIA) Controllers
Bit 5 — Card Is I/O
Memory Card Interface mode: card socket configured to support memory cards. Dual-function
socket interface pins perform memory card-type interface functions.
0
1
I/O Card Interface mode: card socket configured to support I/O/memory card-type interface
functions. Dual-function socket interface pins perform I/O/memory card-type interface functions.
This bit determines how dual-function socket interface pins will be used.
Bit 6 — Card Reset*
0
1
The RESET signal to the card socket is set active (high for normal, low for ATA mode).
The RESET signal to the card socket is set inactive (low for normal, high for ATA mode).
This bit determines whether the RESET signal (see Table 2 on page 20) to the card is active or
inactive. When the Card Enable bit (see “Bit 7 — Card Enable” on page 50) is ‘0’, the RESET
signal to the card will be high-impedance. See Chapter 10 for further description of ATA mode
functions.
Bit 7 — Ring Indicate Enable
0
1
BVD1/-STSCHG pin is status change function.
BVD1/-STSCHG pin is ring indicate input pin from card.
This bit determines whether the -STSCHG input pin is used to activate the IRQ15 pin in
conjunction with Misc Control 2, IRQ15 Is RI Out (see “Bit 7 — IRQ15 Is RI Out” on page 74).
This bit has no significance when the card socket is configured for memory card operation.

• This register indicates the source of a management interrupt generated by the PD67XX.
Note: The corresponding bit in the Management Interrupt Configuration register must be set to ‘1’ to
enable each specific status change detection.
