7.3.6 CHASE control
Table 10.
Legend: * default value.
CHASE is used to program the LED output ON/OFF pattern. The contents of the CHASE
register is used to enable one of the LED output patterns, as indicated in
By repeated, sequential access to this table via the CHASE register, a chase pattern, e.g.,
marquee effect, can be easily programmed with minimal number of commands. Once the
CHASE register is accessed, the data bytes that follow will be used as an index value to
pick the LED output patterns defined by
This register always updates on ACK. It is used to gate the OE signal at each of the LEDn
pins such that:
Any write to this register takes effect at the ACK.
