Section 29 PC Card Controller (PCC)
Bit Bit Name Initial Value R/W Description
2
P0CD1
Undefined* R PCC0 Card Detect 1
The value of CD1 pin of the PC card connected to area
6 is read. This bit cannot be written to.
0: The value of CD1 pin of the PC card connected to
area 6 is 0
1: The value of CD1 pin of the PC card connected to
area 6 is 1
1
P0BVD2/ Undefined* R PCC0 Battery Voltage Detect 2 and 1
P0SPKR
The values of BVD1 and BVD2 pin of the PC card
0
P0BVD1/ Undefined* R connected to area 6 are read when the IC memory card
P0STSCHG
interface is connected. The values of STSCHG and
SPKR pin of the PC card connected to area 6 are read
when the I/O card interface is connected. These bits
cannot be written to.
(1) The following applies to the IC memory interface.
11: The battery voltage of the PC card connected to
area 6 is normal (Battery Good)
01: The battery must be changed although data is
guaranteed for the PC card connected to area 6
(Battery Warning)
x0: The battery voltage is abnormal and data is not
guaranteed for the PC card connected to area 6
(Battery Dead)
(2) The values of bits 1 and 0 for the I/O card interface
are as follows:
0: The value of STSCHG or SPKR of the PC card
connected to area 6 is 0
1: The value of STSCHG or SPKR of the PC card
connected to area 6 is 1
Note: * Differs depending on the state of the PC card.
