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-
quest
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
- during soft reset
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
value respectively.

Description
number of retries in case of not acknowledge and busy
status of the transmit telegram buffer
length of the frame in the transmit buffer (bit 8) ¹⁾
length of the frame in the transmit buffer (bits 7 ... 0) ¹⁾
264 Byte transmit buffer
64 Byte receiving frame buffer
1) The length of the frame gives the number of bytes stored in the frame transmit buffer including all frame overhead.

ACK : number of retries in case of not acknowledge (either NACK on no ack frame)
BUSY : number of retries in case of busy (BUSY or simultaneously BUSY and NACK)
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
value respectively.
