NOTES:
Revision 0.1 (06-07-07)
The communication function unit will start operation within 1.0 μs (at 2.5 Mbps) after releasing software reset. It is
therefore necessary to wait for at least 1.0 μs (at 2.5 Mbps) after releasing software reset before writing data to
the register reset by software (see previous page). The writing can be ignored.
After 10 μs (at 2.5 Mbps) following the software reset, D1h is written to address = 0 in page #00 of the RAM and
node ID value is written to the address = 1.
Values in text are at 2.5 Mbps. When 1.25 Mbps, the value should be doubled accordingly. When 5 Mbps, the
value should be half of 2.5Mbps’
Software reset: Resets only the units related to communication functions.
How to software reset
1)
Set the RESET bit of the COMR6 register to 1
(Retains until the bit is changed to 0)
Set the node ID set to 00h
(Retains until the setting is changed to other than 00h)
2)
Software reset occurs for 100 ns (at 20 MHz CLK input) immediately after rewriting the object bits or writing
the object registers. This reset is automatically released.
Rewriting INIMODE bit of the MODE register
Rewriting TXEN bit of COMR6 or MODE register from 0 to 1
Rewriting the following registers for INIMODE = 1
Permanent software reset
Temporary software reset
MAXID register
NID register
PS register
CKP register
The reset method is described as below.
