0x001C - Mainboard

	System requirements This module is not supported by all devices, since it requires a special BIOS. If your device does not support this module, the program will issue error message 0xECA60105 ("No data available"). See also: System requirements

08	VAR	PIN7	UNSIGNED8	read-only / read-write

¹ From MDP version 1.0.7.14.

The table 0x8nn7 contains the current status (1 or 0) of each individual pin of GPIO1.

Depending on whether the pin is an input or an output, the access changes. If it is an input, access is read-only. Outputs can be written and therefore have read-write access.

0x8nn8 – GPIO1 In/Out¹

SubIndex	Type	Name	Type	Access
00	VAR	Len	UNSIGNED16	read-only
01	VAR	PIN0	UNSIGNED8	read-only
02	VAR	PIN1	UNSIGNED8	read-only
03	VAR	PIN2	UNSIGNED8	read-only

05	VAR	PIN4	UNSIGNED8	read-only
06	VAR	PIN5	UNSIGNED8	read-only
07	VAR	PIN6	UNSIGNED8	read-only
08	VAR	PIN7	UNSIGNED8	read-only

¹ From MDP version 1.0.7.14.

Table 0x8nn8 can be used to determine whether PIN(X) is an output or an input.

Output = 0; Input = 1

The tables 0x8nn7 and 0x8nn8 are structured so that the same subindex provides the data of the same PIN.

Example:

SubIndex 1 from table 0x8nn7 contains the status of PIN0.
SubIndex 1 from table 0x8nn8 indicates whether PIN0 is an input or output.
…
SubIndex 8 from table 0x8nn7 contains the status of PIN7.
SubIndex 8 from table 0x8nn8 indicates whether PIN7 is an input or output.
