Note -: The initial value is determined by the status of the PC card.
The PCC0 interface status register (PCC0ISR) is an 8-bit READ-only register, which reads the
status of the PC card connected to PCC0. PCC0ISR is subject to the PC card status.
Bit
Description
Default
7
PCC0 Ready/IREQ0 Pin Status (P0READY/IREQ0)
If this bit is high: Indicates that the value of pin PCC0RDY is 1 when the PC card
connected to PCC0 is the IC memory card interface. Indicates that the value of pin IREQ
is 1 when the I/O and Memory card interface is the PC card connected to PCC0.
If this bit is low: Indicates that the value of pin PCC0RDY is 0 when the PC card
connected to PCC0 is the IC memory card interface. Indicates that the value of pin IREQ
is 0 when the I/O and Memory card interface is the PC card connected to PCC0.
-
6
PCC0 Memory Write Protect (P0MWP)
If this bit is high: Indicates that the value of pin PCC0WP is 1 when the Memory card
interface is the PC card connected to PCC0.
If this bit is low: Indicates that the value of pin PCC0WP is 0 when the PC card connected
to PCC0 is the IC memory card interface. The value of bit 6 is always 0 when the I/O and
Memory card interface is the PC card connected to PCC0.
