†
The Motorola Interconnect Bus (MI BUS) is a serial communications protocol which supports
distributed real-time control efficiently and with a high degree of noise immunity. It allows data
to be transferred between the MCU and the slave device using only one wire, making this type
of communication suitable for medium speed networks requiring very low cost multiplex
wiring.
option is always available, the PLL oscillator is optimized for operation at 32 kHz, the
oscillator buffer is an inverter, the POR/exit from STOP start-up time is 4064 bus cycles
and the ROMON bit is software switchable in user expanded mode.
These options are not available on the MC68HC711PH8; on this device, the security
