• Bit 6: (RX_TEL_VALID)
The RX_TEL_VALID bit is set or cleared if the received Easywave
telegram changes while being in Receive Mode. If an Easywave
telegram has been recived which differs from the preceding one, the
RX_TEL_VALID bit is set to 1. If there is not any further valid
Easywave telegram received, the RX_TEL_VALID bit is set to 0.
The RX_TEL_VALID bit is used together with the RX_TEL_CHANGED
bit. (Please refer to “Receiving of Easywave Telegrams“ on page 19.)
0x02 RX_CHANNEL Rx Channel register. It specifies the channel number (0...31) while
receiving or learning of an Easywave telegram, or while deleting of a
learned Easywave telegram.
The RX_CHANNEL register changes its content upon receiving of an
Easywave telegram.
The RX_CHANNEL register also specifies what channel's user data the
RX_USERDATA0 and RX_USERDATA1 registers map.
The RX_CHANNEL register is a read-write register.
(Please refer to “Receiving of Easywave Telegrams“ on page 19,
“Learning of Easywave Telegrams“ on page 21, and “Delete Learned
Easywave Telegrams“ on page 22.)
0x03 RX_BUTTON Rx Button register. It specifies the button number while receiving or
learning of an Easywave telegram.
The RX_CHANNEL register is a read-write register; a write to the
RX_CHANNEL register modifies the register's content, but has not any other
effect.
One of the following values can be read or written:
• 0x00 Easywave Button A (“On“ or “Up“);
• 0x01 Easywave Button B (“Off“ or “Down“);
• 0x02 Easywave Button C (“Stop“);
• 0x03 Easywave Button D (“Stop“)
(Please refer to “Receiving of Easywave Telegrams“ on page 19,
“Learning of Easywave Telegrams“ on page 21, and “Delete Learned
Easywave Telegrams“ on page 22.)
0x04 RX_USERDATA0 Rx User Data Byte#0 register. The RX_USERDATA0 register maps an
opaque user data byte here which the transceiver module stores
associated with each channel.
The I 2 C master can store some data here. Since the RX_CHANNEL register
contains the channel number of a received Easywave telegram, the
RX_USERDATA0 register automatically maps the user data byte value
which is associated with the received Easywave telegram.
The RX_USERDATA0 register is a read-write register.
The transceiver module stores the user data bytes in persistent storage.
Note that the current implementation interrupts any receive attempts of
Easywave telegrams while the persistent storage is written.
