Conguration Locking
The security register, LOCK, provides the ability to disable
conguration changes as they apply to the MIC280s most
critical functions: shutdown mode, and reporting diode faults
and over-temperature events. LOCK provides a way to prevent
malicious or accidental changes to the MIC280 registers that
might prevent a system from responding properly to critical
events. Once L0, L1, or L2 has been set, the global interrupt
enable bit, IE, will be set and xed. It cannot subsequently be
cleared. Its state will be reected in the conguration register.
The bits in LOCK can only be set once. That is, once a bit is
set, it cannot be reset until the MIC280 is power-cycled or a
warm reset is performed by setting RST in the conguration
register. The warm reset function can be disabled by setting
L4 in LOCK. If L4 is set, locked settings cannot be changed
during operation and warm resets cannot be performed; only
a power-cycle will reset the locked state(s).
If L0 is set, the values of IM0 and CRIT0 become xed and
unchangeable. That is, writes to CRIT0 and the corresponding
interrupt enable bit are locked out. A local over-temperature
event will generate an interrupt regardless of the setting of
IE or its interrupt mask bit.
If L1 is set, the values of IM1 and CRIT1 become xed and
unchangeable. A remote over-temperature event will gener-
ate an interrupt regardless of the setting of IE or its interrupt
mask bit. Similarly, setting L2 will x the state of IM2, allow-
ing the system to permanently enable or disable diode fault
interrupts. A diode fault will generate an interrupt regardless
of the setting of IE or its interrupt mask bit.
L3 can be used to lock out shutdown mode. If L3 is set, the
MIC280 will not shut down under any circumstances. Attempts
to set the SHDN bit will be ignored and all chip functions will
remain operational. If L3 is set while the MIC280 is in shutdown
mode, it will immediately exit shutdown mode and resume
normal operation. It will not be possible to subsequently re-
enter shutdown mode.
Setting L4 disables the RST bit in the conguration register,
preventing the host from initiating a warm reset. Writes to
RST will be completely ignored if L4 is set.
LOCK BIT
FUNCTION LOCKED
RESPONSE WHEN SET
L0
Local over-temperature detection
IM0 xed at 1, writes to CRIT0 locked-out; IE permanently set
L1
Remote over-temperature detection
IM1 xed at 1; writes to CRIT1 locked-out; IE permanently set
L2
Diode fault interrupts locked on or off
IM2 xed at current state; IE permanently set if IM2=1
L3
Shutdown mode
SHDN xed at 0; exit shutdown if SHDN=1 when L3 is set
L4
Warm resets
RST bit disabled; cannot initiate Warm resets
