7.1.2 GPIO_Write Command and its Response

The GPIO_Write command (0x64) configures the specified GPIO output pin to the selected logic state.

This command is sent through Endpoint 0x04 (OUT). The response is read through Endpoint 0x84 (IN).

Table 7-4. `GPIO_Write` - Command
Byte Index	Command		Description
0	`0x64`	Command code	Sets the specified GPIO pin to the specified state
1	`0x00` `0x01` `0x10` `0x11` `0x20` `0x21` `0x30` `0x31` `0x40` `0x41` `0x50` `0x51`	GPIONum-GPIOStat: GPIO0 Low GPIO0 High GPIO1 Low GPIO1 High GPIO2 Low GPIO2 High GPIO3 Low GPIO3 High GPIO4 Low GPIO4 High GPIO5 Low GPIO5 High	GPIO pin and its output state

Table 7-5. `GPIO_Write` - Response
Byte Index	Response		Description
0	`0x64`	Returns command code	Returns whether the `GPIO_Write` command was accepted
1	`0x20`	Accepted - success	Accepted, and the output state is written
	`0x60`	Rejected – invalid pin number	Rejected because the pin number is invalid
	`0x68`	Rejected – not a GPIO	Rejected because the selected pin is not configured as a GPIO
