MAX7313
Command Address Autoincrementing
The command address stored in the MAX7313 circu-
lates around grouped register functions after each data
byte is written or read (Table 2).
Device Reset
If a device reset input is needed, consider the
MAX7314. The MAX7314 includes a RST input, which
clears any transaction to or from the MAX7314 on the
serial interface and configures the internal registers to
the same state as a power-up reset.
Detailed Description
Initial Power-Up
On power-up all control registers are reset and the
MAX7313 enters standby mode (Table 3). Power-up
status makes all ports into inputs and disables both the
PWM oscillator and blink functionality.
Configuration Register
The configuration register is used to configure the PWM
intensity mode, interrupt, and blink behavior, operate
the INT/O16 output, and read back the interrupt status
(Table 4).
