INTI is asserted when I
read is performed on the I
PWM, constant-current circuits, and GPIs are shut down. GPO
values depend on their setting. Register 0x41 to 0x5F values are
stored and cannot be changed. The entire part is shut down if the
key switches are in sleep mode (D7 of register 0x01).
Normal GPIO operation. PWM, constant-current circuits, and GPIOs
are enabled regardless of key-switch sleep mode state (see Table 8).
Normal operation
Return all GPIO registers (registers 0x40 to 0x5F) to their POR
value. This bit is momentary and resets itself to 0 after the write
cycle.
No fading
PWM intensity ramps up (down) between the common PWM value
and 0% duty cycle in 16 steps over the following time period:
D[2:0] = 001 = 256ms
D[2:0] = 010 = 512ms
D[2:0] = 011 = 1024ms
D[2:0] = 100 = 2048ms
D[2:0] = 101 = 4096ms
D[2:0] = 110/111 = Undefined
