6.6.2 SGPIO Programmable Blink Register x — SGPBRx
This SGPIO Programmable Blink Register x - SGPBRx is used to program the
programmable blink patterns. Each output signal supports two programmable blink
patterns and each pattern can be programmed using two 4-bit fields. The two 4-bit
fields allow the user to program a low and a high duration time. The shortest low/high
duration time that can be programmed is 125 ms, whereas the longest low/high
duration time that can be programmed is two seconds.
