PD6710/’22 — ISA-to-PC-Card (PCMCIA) Controllers
7.5
Bit 5 — Card Is I/O
0
Memory Card Interface mode: card socket configured to support memory cards. Dual-function
socket interface pins perform memory card-type interface functions.
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
The RESET signal to the card socket is set active (high for normal, low for ATA mode).
1
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
BVD1/-STSCHG pin is status change function.
1
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.
