Multipurpose LED Bank 2H Output
These bits control the Multipurpose LED Bank 2 pins
MPLED2_4, MPLED2_5, MPLED2_6, and MPLED2_7.
Two bits 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 2L Input
The bits in this read only register read the live input value
on the MPLED2_0, MPLED2_1, MPLED2_2, and
MPLED2_3 pins. If these pins are 3-stated using the
Multipurpose LED Bank 2 Output Registers (0xFF38,
0xFF39), they can be used as input pins.
