*GPIO2 Data Port ⎯ Index 08h
Bit
Name
R/W Reset Default
Description
GPIO2 Data Control, this byte is available when GPIODEC_RANGE is set.
Write data to this byte will change the value of GPIO20_VAL ~ GPIO27_VAL
7-0
GPIO2_DATA R/W 5VSB
- in configuration register as writing data to index 0xD1.
Read data from this byte will read the pin status of GPIO20_IN ~ GPIO27_IN
as the value in index 0xD2
*GPIO3 Data Port ⎯ Index 09h
Bit
Name
R/W Reset Default
Description
GPIO3 Data Control, this byte is available when GPIODEC_RANGE is set.
Write data to this byte will change the value of GPIO30_VAL ~ GPIO37_VAL
7-0
GPIO3_DATA R/W LRESET# - in configuration register as writing data to index 0xC1.
Read data from this byte will read the pin status of GPIO30_IN ~ GPIO37_IN
as the value in index 0xC2
GPIO4 Data Port ⎯ Index 0Ah
Bit
Name
R/W Reset Default
Description
GPIO4 Data Control, this byte is available when GPIODEC_RANGE is set.
Write data to this byte will change the value of GPIO40_VAL ~ GPIO47_VAL
7-0
GPIO4_DATA R/W LRESET# - in configuration register as writing data to index 0xB1.
Read data from this byte will read the pin status of GPIO40_IN ~ GPIO47_IN
as the value in index 0xB2
6.6.2 GPIOxx status
Z means high impendence.
If the external circuit is pull high then the pin status is "H"; else if the external circuit is pull low then the pin
status is "L".
User define means by programming the configure register.
