Multipurpose LED Bank 0H Output
The bits in this register control the Multipurpose LED
Bank 0 pins MPLED0_7, MPLED0_6, MPLED0_5, and
MPLED0_4. Two bits are used to control each LED,
according to
The slow blink and fast blink rates are defined in the
Blink Rate (LBR)
16 mA open drain drivers. Turning the LED off
(MLOx_xA = 0 and MLOx_xB = 0) effectively 3-states the
driver.
Reserved
Multipurpose LED Bank 0L Input
The bits in this read only register read the live input value
on the MPLED0_0, MPLED0_1, MPLED0_2, and
MPLED0_3 pins. If these pins are 3-stated using the
Multipurpose LED Bank 0 Output registers (0xFF30,
0xFF31), they can be used as input pins.
