Device	Manufacturer	Specification
BR24T1M_3AM	Rohm	128Kx8 Serial EEPROM1

Usage example

use avr_oxide::hardware;
use avrox_storage::{serprom,RandomRead};
use avr_oxide::devices::serialbus::UsesSerialBusClient;

#[avr_oxide::main(chip="atmega4809",stacksize=512)]
pub fn main() {
  let supervisor = avr_oxide::oxide::instance();

  let bus = StaticWrap::new(OxideSerialBus::using_bus(hardware::twi::twi0::instance().mux(hardware::twi::twi0::TwiPins::MasterASlaveC).mode(InterfaceMode::I2C, PortSpeed::Fast)));
  supervisor.listen(bus.borrow());
  let serprom = serprom::BR24T1M_3AM::using_client(OxideSerialBus::client(bus.borrow(), TwiAddr::addr(0xA0)));

  let mut buffer = [ 0x00u8, 0x00u8, 0x00u8, 0x00u8 ];
  serprom.read_at(0u32, &mut buffer);
}
