This section demonstrates how to read status of a GPIO pin (FPWM8_GPIO12).

The Pid ID of the FPWM8_GPIO12 is 7 from Table 3-1Table 3-2.

Application need sends out the following commands:

Write GPIO_SELECT command to choose the target GPIO. Payload 0x07 is to select FPWM8_GPIO12 pin,

• [St] [AddrW] [A] [W:0xFA] [A] [W:0X07][A][Sp]

Read GPIO_CONFIG command to get the status of FPWM8_GPIO12

• [St] [AddrW] [A] [W:0xFB] [A] [SR][Addr][A][R:data][N][Sp]

If the bit 3 of the return data is 1, the signal of the FPWM8_GPIO12 is HIGH otherwise it is LOW.
