Receive Interrupt Enable Register
This register provides control for enabling or masking
interrupts based on the assertion of status bits in DCLR1,
the Receive Status Register. See Table 7.
Transmit Mode Register
This register contains two control bits associated with
transmission, a general-purpose control bit which drives
a pin on the chip, and a collision counter. See Table 9.
