T1MD Timer1 Mode
0 = Single mode: The timer counts once and generates a T1EXP interrupt when expires.
1 = Periodical mode: The timer counts periodically and generates an interrupt at each expiration.
CNT6-0 Count Value
The expiration time is defined as:
T1 = CNT[6:0] * 0.1 second
After writing this register, STT1 bit in D_CMDR register must be set to start the timer. This register
can be read only after the timer has been started. The read value indicates the timer's current count
value. In case layer 1 is not activated, a C/I command "ECK" must be issued in addition to the STT1
command to start the timer.
The timer is stopped when it expires (T1MD = 0) or TIMR1 register is re-written.

D_RMR D_ch Receive Message Ready
A 64-byte data is available in the D_RFIFO. The frame is not complete yet.
D_RME D_ch Receive Message End
The last part of a frame with length > 64 bytes or a whole frame with length
≤
64 bytes has been
received. The whole frame length is obtained from D_RBCH + D_RBCL registers. The length of data
in the D_RFIFO equals:
data length = RBC5-0 if RBC5-0
≠
0
data length = 64 if RBC5-0 =0
D_XFR D_ch Transmit FIFO Ready
This bit indicates that the transmit FIFO is ready to accept data. Up to 64 bytes of data can be written
into the D_XFIFO.
