Table 38. KNX address register
Table 39. Status of the KNX address
1) Access via UART service and SPI possible. In case of hard or soft reset the register is reset to the hard reset value or soft reset
Table 40. Telegram transmission register
1) The length of the frame gives the number of bytes stored in the frame transmit buffer including all frame overhead.
Table 41. MAX_RST_CNT
1) Access via UART service and SPI possible. In case of hard or soft reset the register is reset to the hard reset value or soft reset

VALID :
"1": the stored address is valid
"0": the stored address is invalid
the bit is set by the host by writing to the register or by using U_SetAddress service re-

it is reset. If the Address is configured by SPI the User have to set this bit too.
- by the host by writing to the register and
