Description
PCC0IREQ Request Enable
These bits enable or disable IREQ interrupt requests
and select the interrupt mode when the PC card
connected to area 6 is the I/O card interface type. Note
that bit 5 (P0IREQ) in the area 6 card status change
register (PCC0CSCR) is cleared if the values in bits 6
and 5 in this register are changed. These bits have no
meaning on the IC memory card interface.
00: IREQ requests are not accepted for the PC card
01: The level-mode IREQ interrupt request signal is
10: The pulse-mode IREQ interrupt request signal is
11: The pulse-mode IREQ interrupt request signal is
PCC0 Status Change Enable
When the PC card connected to area 6 is on the I/O
card interface, bit 4 enables or disables the interrupt
request when the value of the BVD1 (STSCHG) is
changed. This bit has no meaning in the IC memory
card interface.
0: No interrupt occurs for the PC card connected to
1: An interrupt occurs for the PC card connected to
area 6 regardless of the value of the BVD1
(STSCHG)
area 6 when the value of the BVD1 (STSCHG) is
changed from 1 to 0
connected to area 6. Bit 5 in the status change
register (PCC0CSCR) functions as a read-only bit
that indicates the inverse of the IREQ signal.
accepted for the PC card connected to area 6. In
level mode, an interrupt occurs when level 0 of the
signal input from the IREQ is detected.
accepted for the PC card connected to area 6. In
pulse mode, an interrupt occurs when a falling edge
from 1 to 0 of the signal input from the IREQ is
detected.
accepted for the PC card connected to area 6. In
pulse mode, an interrupt occurs when a rising edge
from 0 to 1 of the signal input from the IREQ is
detected.
