Specification Index 1.01 Project No. RF-Products, Controller RTRM08 Transceiver Module Easw I 2 C Page 2 Development Production S. Schreiber 2007-08-24 Revision History Index Releases 0.90 Initial Release. 1.00 Section 1 and section 2.1: Options for the antenna are mentioned now. Section 2.3: 7007 Some figures have been corrected. The acknowledge bit A- after the final data byte of a read transfer is labeled with “1“ now (Figure 4, Figure 5, Figure 7, Figure 8). It is stated now that the current implementation interrupts any receive attempt of Easywave telegrams while the persistent storage is written (RX_USERDATA0 and RX_USERDATA1 registers). It is stated that any bit is cleared in the RX_LN_CHXXX registers when ELDAT ships the transceiver module RTRM08. 1.01 Section 1, section 2.1, and section 3.2: The upper limit of the power supply's operational range of 5.5 V has been decreased to 5.25 V.
