6.4.2 Programmable Blink Patterns
Each of the SGPIO output signal supports two programmable blink patterns that can be
selected using the Table 328, “SGPIO Output Data Select Register[0:7] x -
SGODSR[0:7]x” on page 484 . The blink rate generator is clocked using an 8 Hz clock
and allows the user to program a low and a high duration time using two 4-bit fields
located in the Table 322, “SGPIO Programmable Blink Register x - SGPBRx” on
page 476 . The shortest low/high duration time that can be program is 125 ms and the
longest low/high duration time that can be programmed is 2 seconds. The shortest
blink rate period is 250 ms and the longest blink rate period is 4 seconds.
