Mask options
Mask options
There are two mask options on the MC68HC05E6 which are
programmed during manufacture and therefore must be specified on the
order form; COP watchdog timer enable/disable and STOP instruction
enable/disable.
LVI/options
register (LVI/OPT)
In addition, the IRQ pin can be configured to be either edge or
edge-and-level sensitive. This is done using the IRQ bit in the
LVI/options register at $0F.
There are two options on the MC68HC705E6 which are programmed
using configuration bits in the LVI/options register; COP watchdog timer
enable/disable and edge or edge-and-level sensitive IRQ triggering. The
STOP instruction is permanently enabled on the MC68HC705E6.
LVI/options (LVIOPT)
Address bit 7 bit 6 bit 5 bit 4 bit 3
$000F LVIINT LVIVAL LVIRST LVIENA
bit 2
bit 1
bit 0
State
on reset
COP IRQ 0u00 0u00
COP — Computer operating properly watchdog enable/disable
1 = COP watchdog disabled.
0 = COP watchdog enabled.
Reset clears this bit, thus the COP watchdog is enabled automatically
after reset. Because of the ‘write-once’ nature of the COP bit, it is
recommended that it be written to immediately after reset to lock the
desired state.
IRQ — Interrupt triggering sensitivity
1 = IRQ is negative edge-and-level sensitive
0 = IRQ is negative edge sensitive only
Reset clears the IRQ bit.
NOTE:
The bits in the LVIOPT register which are shaded are not relevant to this
section of the data sheet. These bits are described in Resets and
Interrupts.
