output port registers, and using the software or hard-
ware controls to flip between the patterns.
If the blink phase 1 register is written with 0xFF, then
the BLINK input can be used as a hardware disable to,
for example, instantly turn off an LED pattern pro-
grammed into the blink phase 0 register. This technique
can be further extended by driving the BLINK input with
a PWM signal to modulate the LED current to provide
fading effects.
The blink mode is enabled by setting the blink enable
flag E in the configuration register (Table 4). When blink
mode is enabled, the state of the blink flip flag sets the
phase, and the output ports are set by either the blink
phase 0 register or the blink phase 1 register (Table 7).
The blink mode is disabled by clearing the blink enable
flag E in the configuration register (Table 4). When blink
mode is disabled, the blink phase 0 register alone con-
trols the output ports.
Blink Phase Registers
When the blink function is disabled, the blink phase 0
register sets the logic levels of the 8 ports (P0 through
P7) when configured as outputs (Table 8). A duplicate
register called the blink phase 1 register is also used if
the blink function is enabled (Table 9). A logic high sets
the appropriate output port high impedance, while a
logic low makes the port go low.
