Freescale Semiconductor
The current flow detection amplifier is used to detect charge and
discharge current flowing through an external sensing resistor, R
The current flow detection flag CDIF is set when the voltage at OPIN1
exceeds –9mV (typical) (0.9 ampere when R
CDIF can generate an interrupt request to the CPU when the analog
module interrupt enable bit AMIEN is set (see
The current detect flag, CDIF, can be configured for direct control to
other external circuitry. When the CDOEN bit in CONFIG2 is set, the
status of CDIF is reflected on the PTC0/PWM0/CD pin. (See
Configuration Register 2 (CONFIG2)
When the AMIEN bit is set, the analog module is capable of generating
CPU interrupt requests. The interrupt vector is defined in
Vector
The STOP and WAIT instructions put the MCU in low power-
consumption standby modes.
In wait mode the analog module if enabled, continues to operate and
may generate an interrupt to trigger the MCU out of wait mode.
In stop mode, the temperature sensor and the two-stage amplifier are
disabled, but the current flow detection amplifier (when enabled)
continues to operate if the oscillator is enabled in stop mode. When
AMIEN is set, CDIF can be used to wake-up the MCU from the stop
mode.
