CDC_ACM_GPIO_INT_MASK_LSB (0x00D) - Read/Write OTP
Bit
7:0
Default
Description
0x0
GPIO Interrupt Mask of GPIO[7:0]
0: A change in the input pin's state causes the device to generate an interrupt packet
1: A change in the input pin's state does not cause the device to generate an interrupt packet
CDC_ACM_GPIO_INT_MASK_MSB (0x00E) - Read/Write OTP
Bit
7:3
2
1:0
Default
Description
0
Reserved
These bits are reserved and should be written as ‘0’.
0
GPIO Interrupt Mask of RX
0: A change in the input pin's state causes the device to generate an interrupt packet
1: A change in the input pin's state does not cause the device to generate an interrupt packet
0x100
GPIO Interrupt Mask of GPIO[9:0]
0: A change in the input pin's state causes the device to generate an interrupt packet
1: A change in the input pin's state does not cause the device to generate an interrupt packet
