Pin Description
2.6 XOUT
2.7 E-Clock Output (E)
2.8 Interrupt Request (IRQ) and Non-Maskable Interrupt (XIRQ)
Technical Data
38
NOTE:
The XOUT pin provides a buffered clock signal if enabled to synchronize
external devices with the MCU. See
This signal is not present on the 80-pin M68HC(7)11K device QFP
package.
The internally generated instruction cycle clock, or E clock, is available
on the E pin as a timing reference. Its frequency is one fourth the input
frequency at the XTAL and EXTAL pins. The E clock is low during the
address portion of a bus cycle and high during the data access portion
of the bus cycle. All clocks, including the E clock, are halted when the
MCU is in stop mode. The E-pin driver can be turned off in single-chip
modes to reduce radio frequency interference (RFI) and current
consumption.
The MCU provides two pins for applying asynchronous interrupt
requests. Interrupts applied to the IRQ pin can be masked by setting the
I bit in the condition code register (CCR), which can be set or cleared by
software at any time. Triggering is level sensitive by default, which is
