Anachip AM24LC21 Dual Mode 1K-bits (128 x 8) 2-Wire Serial EEPROM (Preliminary) handbook
The Anachip AM24LC21 is a 1K-bits (128 x 8) Electrically Erasable PROM designed for storing and transmitting configuration and control information. It features a dual-mode interface: a transmit-only mode for unidirectional data output and a bi-directional mode for standard read/write operations compatible with I2C protocols. The device operates on a single supply voltage ranging from 2.5V to 5.5V.

Questions answered in these manuals
What are the two modes of operation for the AM24LC21?
The device operates in transmit-only mode and bi-directional mode.
From: Anachip AM24LC21 Dual Mode 1K-bits (128 x 8) 2-Wire Serial EEPROM (Preliminary) handbook
How does the device switch from transmit-only to bi-directional mode?
A valid high to low transition on the SCL pin causes the device to enter bi-directional mode.
