Figure 5–6. Transmitter Configurations
5.11 Receiver Configurations
As with the transmitter configurations, the TMS3637 uses the last nine bits of the 31 data bits stored in
memory to program the device for a multitude of receiver configurations (48 possible configurations). The
configuration must match the transmitter when selecting the receiver configuration (see Table 5–6 to
determine compatible transmitter and receiver combinations). The definition of which configuration bits to
set for all the possible 48 receiver configurations is discussed in Section 5.12.
In the receive mode, the TMS3637 receives the transmitted code on IN and compares the code with the code
stored in memory. When the two codes are equal, a valid transmission pulse is sent to OUT. To have reliable
reception of the transmitted code, the receiver clock frequency must be approximately seven times greater
than the clock frequency for the transmitter clock. To set any receiver configuration in the receiver mode,
always start by clearing the EEPROM bits CA = CC = 0.
