NOTE:
Revision 0.1 (06-07-07)
The FARB bit switch must be operated during Software Reset.
RCNTM1, RCNTM0 (bits 1 and 0)
These bits set the timeout time of the reconfiguration timer. The following timeout times are applicable
when the transfer rate is 2.5 Mbps. (The values become half at 5 Mbps)
RCNTM1-0
00
01
10
11
The timeout times above are values for COMR6: Reconfiguration register’s ET1 and ET2 = 1,1
respectively. If ET1 and ET2 are other than the above value, the timeout time is doubled.
(This includes the case of ET1 pin=Low)
Refer to section 2.13.2 - Timer Expansion in Multi-Stage Cascade Connection ET1 pin and section 3.2.7 -
COMR6 register: Configuration Register ET1, ET2 bit for details.
*1 Does not exist in the ARCNET original specification.
- When reading/writing: GPIO Data Register
GPD[7:0] (bit 7-0)
Write : write data which outputs to GPIP7-0 pin
Read : read the state of the GPIO7-0 pin
