A master code (0000 1XXXb) must be issued to place the device in high-speed mode. This enables master/slave communication for speeds up to 3.4 MHz. A stop condition will exit Hs-mode. Serial Data Format in Hs-mode Serial data transfer format in Hs-mode meets the standard-mode I2C-bus specification. Hs-mode can only commence after the following conditions (all of which are in F/S-modes): 1. START condition (S) 2. 8-bit master code (0000 1XXXb) 3. No-acknowledge bit (A) Single and multiple-byte reads and writes are supported. After the device enters into Hs-mode, data transfer continues in Hs-mode until stop condition is sent by master device. The slave switches back to F/S-mode after a STOP condition (P). To continue data transfer in Hs-mode, the master sends Repeated START (Sr). See Figure 13 on page 11 and Figure 16 on page 12 for Hs-mode timings for read and write operation. Figure 5.
