2.2 CPU BUS SIGNAL DESCRIPTION
Signal Name:
CMS
Signal Description:
CPU Bus Mode Select
Signal Type:
Input
This signal should be tied low when the device is to be operated as a 16-bit bus. This signal should be
tied high when the device is to be operated as an 8-bit bus.
0 = CPU Bus is in the 16-Bit Mode
1 = CPU Bus is in the 8-Bit Mode
Signal Name:
CIM
Signal Description:
CPU Bus Intel/Motorola Bus Select
Signal Type:
Input
The signal determines whether the CPU Bus will operate in the Intel Mode (CIM = 0) or the Motorola
Mode (CIM = 1). The signal names in parenthesis are operational when the device is in the Motorola
Mode.
0 = CPU Bus is in the Intel Mode
1 = CPU Bus is in the Motorola Mode
