GMS30C7201 Datasheet, PDF (113/352 Pages) Hynix Semiconductor – 60MHz operation frequency Low power consumption

PCMCIA Interface
Bit Description
0
Card Power Down Mode
0: Power is supplied to Socket
1: Power is not supplied to Socket. Card Power Down Mode
Although the PC card is in the socket, the power is not supplied to the
socket. So, there are large system power savings.Software Card Detect
Interrupt is required to exit from Card Power Down Mode
d)
Card Status Interrupt Configuration Register: Masking Register for Interrupt
Bit Description
7
Ring Indicate / Status Changed Mask
0: RI/nSTSCHG interrupt masked
1: RI/nSTSCHG interrupt enabled
6
Card Detect Enable
1 for enable
0 for masking
5–4 PC card generated Interrupt (nIREQ) enable
00: PC card generated interrupt (nIREQ) is not enabled
01 The level-mode IREQ interrupt request signal is accepted
An interrupt occurs when 0 is detected at nIREQ pin.
10: The pulse-mode IREQ interrupt request signal is accepted
An interrupt is occurs when the falling edge is detected from nIREQ pin
11: The pulse-mode IREQ interrupt request signal is accepted
An interrupt is occurs when the rising edge is detected from IREQ pin.

Ring Indicate Enable
1 for enable
0 for masking
(No meaning in Memory Card)
2
Ready Enable
1for enable
0 for masking
(No meaning in I/O Card)
1
Battery Warning Enable
1 for enable
0 for masking
0
Battery Dead Enable
1 for enable
0 for masking
In I/O Card, if Ring Indicate Enable bit is 0, nSTSCHG to 0 interrupt source
is enabled
