Description
Slave Address Mask 6 to 0
Correspond to the SVA6 to SVA0 bits in SAR and control
comparison conditions for addresses set in SAR and
addresses of upper 7 bits of the first frame received after a
start condition in slave mode.
0: Compare addresses set in bits SVA6 to SVA0 in SAR
1: Operate assuming that receive addresses have matched
Transmit Mode Switch Mask
Controls automatic switching of transmit modes by the
eighth bit of the first frame in slave mode.
0: When the eighth bit of the first frame is 1, the TRS bit in
1: The TRS bit in ICCRA and TDRE bit in ICSR are not
and receive addresses
bits SVA6 to SVA0 in SAR
ICCRA and TDRE bit in ICSR are automatically set to 1
and a transition is made to slave transmit mode.
automatically changed by the eighth bit of the first
frame.
