ES9033 Datasheet Information

I2C Slave Interface (Device Address 0x90, 0x92, 0x94, 0x96)

This interface contains Read/Write and Read-only registers. A system clock must be present.

Multi-byte registers must be written from LSB to MSB. Data is latched when MSB is written.

Multi-byte registers must be read from LSB to MSB. Data is latched when LSB is read.

MSB is always stored in the highest register address.

Read/Write Register Addresses

Registers 0–88 (0x00 – 0x58) are read/write registers

Read-only Register Addresses

Registers 224 – 241 (0xE0 – 0xF1) are read only registers.

I2C Synchronous Slave Interface (Device Address 0x98, 0x9A, 0x9C, 0x9E)

This interface contains Write-only registers. These registers can be written even when there is no system clock present.

When the device is inactive, all peripherals are automatically disabled and all clocks are stopped. A reset can wake the ES9033.

Write-only Register Addresses.

Registers 192 – 203 (0xC0 – 0xCB) are write only registers.

Multi-Byte Registers

Multi-byte registers must be written from LSB to MSB. Data is latched when MSB is written.

MSB is always stored in the highest register address.
