The area 6 card status change interrupt enable register (PCC0CSCIER) is an 8-bit
readable/writable register. PCC0CSCIER enables or disables interrupt requests for interrupt
sources for the PC card connected to area 6. When a PCC0CSCIER is set to 1, the corresponding
interrupt is enabled, and when the bit is cleared to 0, the interrupt is disabled. PCC0CSCIER is
initialized by a power-on reset but retains its value in a manual reset and in software standby
mode.
Bit 7—PCC0 Card Reset Enable (P0CRE): When this bit is set to 1, and when the CD1 and
CD2 pins detect that a PC card is connected to area 6, the area 6 general control register
(PCC0GCR) is initialized.

Description
The area 6 general control register (PCC0GCR) is not initialized even if a
PC card is detected in area 6
(Initial value)
The area 6 general control register (PCC0GCR) is initialized when a PC
card is detected connected to area 6
