MAX7313
If blinking is enabled, then both interrupt output con-
trols O0 and O1 set the logic state of the INT/O16 pin
according to the blink phase. PWM intensity control for
O16 is set by the 4 global intensity bits in the master
and O16 intensity register (Table 13).
Blink Mode
In blink mode, the output ports can be flipped between
using either the blink phase 0 registers or the blink phase
1 registers. Flip control is by software control (the blink
flip flag B in the configuration register) (Table 4). If hard-
ware flip control is needed, consider the MAX7314, which
includes a BLINK input, as well as software control.
The blink function can be used for LED effects by pro-
gramming different display patterns in the two sets of
output port registers, and using the software or hard-
ware controls to flip between the patterns.
If the blink phase 1 registers are 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 registers. This tech-
nique 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 registers or the blink phase 1 registers (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 state of the blink flip flag is
ignored, and the blink phase 0 registers alone control
the output ports.
Blink Phase Registers
When the blink function is disabled, the two blink phase
0 registers set the logic levels of the 16 ports (P0 through
P15) when configured as outputs (Table 8). A duplicate
pair of registers called the blink phase 1 registers are
also used if the blink function is enabled (Table 9). A
logic high sets the appropriate output port high imped-
ance, while a logic low makes the port go low.
Reading a blink phase register reads the value stored
in the register, not the actual port condition. The port
output itself may or may not be at a valid logic level,
depending on the external load connected.
