Configuration Register
The Configuration Register is a read/write
register which is used to configure the different
modes of the COM20020. The Configuration
Register defaults to the value 0001 1000 upon
hardware reset only. SUBAD0 and SUBAD1
point to selection in Register 7.
Setup Register
The Setup Register is a read/write 8-bit register
accessed when the Sub Address Bits are set up
accordingly (see the bit definitions of the
Configuration Register). The Setup Register
allows the user to change the network speed
(data rate) or the arbitration speed
independently, invoke the Receive All feature,
change the nPULSE1 driver type, and reduce
protocol timeouts by a factor of 3. The data rate
may be slowed to 156.25Kbps and/or the
arbitration speed may be slowed by a factor of
two. The Setup Register defaults to the value
0000 0000 upon hardware reset only.
