15.2.2.3
R1, R0 - Rate Select
These bits determine the operating frequency of the MDLC.
The nominal frequency (f
MDLC) of the MUX Interface clock must always be 1.048576 MHz
in order for J1850 bus communication to take place. Therefore, the value programmed into
these bits is dependant upon the chosen MCU system clock frequency per the following
table.
In the case of R1=R0=0, the oscillator clock is used instead of E clock.
The case of R1=R0=1 must not be selected for the MC68HC05V7 and MC68HC705V8.
15.2.2.4
IE - Interrupt Enable
This bit determines whether the MDLC will generate CPU interrupt requests in the Run
mode. Clearing the IE bit will not prevent CPU interrupt requests when exiting the MDLC
Stop or MDLC Wait modes.
When set, the MDLC will generate CPU interrupt requests. Interrupt requests will be
maintained until all of the interrupt request sources are cleared, by performing the specified
actions upon the MDLC’s registers.
When clear, the MDLC will not generate CPU interrupt requests. Interrupts that were
pending at the time that this bit is cleared may be lost.
15.2.2.5
WCM - Wait Clock Mode
This bit determines the operation of the MDLC during CPU Wait mode. See 15.7.6 MDLC
WAIT MODE for more details on its use.
When set, the MDLC internal operating clocks will be stopped during CPU Wait mode.
When clear, the MDLC internal operating clocks will stay running during CPU Wait mode.
