7.25.1 Reset
7.25.2 Brownout detection
7.25 System control
The first option assumes that power consumption is not a concern and the design ties the
V
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (V
a dedicated 3.3 V supply for the CPU (V
converter powered independently from the I/O pad ring enables shutting down of the I/O
pad power supply “on the fly”, while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC and the battery RAM. These two functions
require a minimum of power to operate, which can be supplied by an external battery.
When the CPU and the rest of chip functions are stopped and power removed, the RTC
can supply an alarm output that may be used by external hardware to restore chip power
and resume operation.
Reset has four sources on the LPC2364/65/66/67/68: the RESET pin, the Watchdog
reset, power-on reset, and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating
voltage attains a usable level, starts the Wake-up timer (see description in
“Wake-up
de-asserted, the oscillator is running, a fixed number of clocks have passed, and the flash
controller has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the Boot Block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
The LPC2364/65/66/67/68 includes 2-stage monitoring of the voltage on the
V
to the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt
Enable Register in the VIC in order to cause a CPU interrupt; if not, software can monitor
the signal by reading a dedicated status register.
The second stage of low-voltage detection asserts Reset to inactivate the
LPC2364/65/66/67/68 when the voltage on the V
Reset prevents alteration of the flash as operation of the various elements of the chip
would otherwise become unreliable due to low voltage. The BOD circuit maintains this
reset down below 1 V, at which point the power-on reset circuitry maintains the overall
Reset.
Both the 2.95 V and 2.65 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.95 V detection to reliably interrupt, or a regularly executed event
loop to sense the condition.
