Section 32 PC Card Controller (PCC)
32.3.3 Area 6 Card Status Change Register (PCC0CSCR)
PCC0CSCR is an 8-bit readable/writable able register. PCC0CSCR bits are set to 1 by interrupt
sources of the PC card connected to area 6 (only bit 7 can be set to 1 as required). PCC0CSCR is
initialized by a power-on reset but retains its value in a manual reset and in software standby
mode.

R/W PCC0 Software Card Detect Change Interrupt
A PCC0 software card detect change interrupt can be
generated by writing 1 to this bit. When this bit is set to
1, the same interrupt as the PCC0 card detect change
interrupt (bit 3 set status) occurs if bit 3 (PCC0 card
detect change enable) in the area 6 card status change
interrupt enable register (PCC0CSCIER) is set to 1. If
bit 3 is cleared to 0, no interrupt occurs.
0: No software card detect change interrupt occurs for
the PC card connected to area 6
1: Software card detect change interrupt occurs for the
PC card connected to area 6

This bit is always read as 0. The write value should
always be 0.
