3.2.11 INTMSK Register: EC Interrupt Mask
3.2.12 ECCMD Register: EC Command Register
Revision 0.1 (06-07-07)
This bit is set if sending fails. Be aware that this function is the opposite of that of the ARCNET-original
TMA bit. This bit is cleared by writing a 1 , issuing the send command, or by a software reset.
TA (bit 0)
This bit is the same as the TA bit of the COMR0: ARCNET status register. (Refer to that register for
details.) This bit becomes 0 only during the send command issuing.
Combination and meaning of transmission status
This register corresponds to interrupt status, and being set to 1, the interrupt signal becomes active when
the corresponding status becomes 1.
ECCMD 7-0 (bits 7 to 0)
This command is unique to CircLink when the bus width is 8 bits (W16 = 0), access to higher bytes is
invalid; the command is executed by access to the lower bytes. When the bus width is 16 bits (W16 = 1),
