NOTE:
NOTE:
STRCH is cleared on reset; therefore, a program cannot execute out of
reset in a slow external ROM.
STRCH is not available on M68HC11K devices.
IRVNE — Internal Read Visibility/Not E Bit
Single-chip
Expanded
Bootstrap
Special test
To use the STRCH feature, ROMON must be set on reset so that the
device starts with internal ROM included in the memory map. STRCH
should then be set.
STRCH has no effect in single-chip and bootstrap modes.
IRVNE can be written once in any user mode. In expanded modes,
IRVNE determines whether IRV is on or off (but has no meaning in
user expanded secure mode, as IRV must be disabled). In special test
mode, IRVNE is reset to 1. In normal modes, IRVNE is reset to 0.
In single-chip modes, this bit determines whether the E clock drives
out from the chip.
Refer to
following reset.

Mode
1 = Data from internal reads is driven out of the external data bus.
0 = No visibility of internal reads on external bus
1 = E pin is driven low.
0 = E clock is driven out from the chip.
