      80C186EC/188EC, 80L186EC/188EC
      pulled low for four clock cycles. Logically ANDing
      the WDTOUT pin with the power-on reset signal al-
      lows the WDT to reset the device in the event of a
      WDT timeout. If a less drastic method of recovery is
      desired. WDTOUT can be connected directly to NMI
      or one of the INT input pins. The WDT may also be
      used as a general purpose timer.
      Power Management Unit
      The 80C186EC Power Management Unit (PMU) is
      provided to control the power consumption of the
      device. The PMU provides four power management
      modes: Active, Powersave, Idle and Powerdown.
      Active Mode indicates that all units on the
      80C186EC are operating at  the CLKIN frequency.
      Idle Mode freezes the clocks of the Execution and
      Bus units at a logic zero state (all peripherals contin-
      ue to operate normally).
      The Powerdown Mode freezes all internal clocks at
      a logic zero level and disables the crystal oscillator.
      In Powersave Mode, all internal clock signals are di-
      vided by a programmable prescalar (up to 1/64 the
      normal frequency). Powersave Mode can be used
      with Idle Mode as well as during normal (Active
      Mode) operation.
      80C187 Interface (80C186EC only)
      The 80C186EC supports the direct connection of
      the 80C187 Numerics Processor Extension. The
      80C187 can dramatically improve the performance
      of calculation intensive applications.
      ONCE Test Mode
      To facilitate testing and inspection of devices when
      fixed into a target system, the 80C186EC has a test
      mode available which forces all output and input/
      output pins to be placed in the high-impedance
      state. ONCE stands for ‘‘ON Circuit Emulation’’,
      The ONCE mode is selected by forcing the
      A19/S6/ONCE pin low during a processor reset
      (this pin is weakly held high during reset to prevent
      inadvertant entrance into ONCE Mode).
      PACKAGE INFORMATION
      This section describes the pin functions, pinout and
      thermal characteristics for the 80C186EC in the
      Plastic Quad Flat Pack (JEDEC PQFP), the EIAJ
      Quad Flat Pack (QFP) and the Shrink Quad Flat
      Pack (SQFP). For complete package specifications
      and information, see the Intel Packaging Outlines
      and Dimensions Guide (Order Number: 231369).

      Pin Descriptions
      Each pin or logical set of pins is described in Table
      2, There are four columns for each entry in the Pin
      Description Table. The following sections describe
      each column.
      Column 1. Pin Name
      In this column is a mnemonic that de-
      scribes the pin function. Negation of the
      signal name (i.e. RESIN) implies that the
      signal is active low.
      Column 2. Pin Type
      A pin may be either power (P), ground
      (G), input only (I), output only (O) or in-
      put/output (I/O). Please note that some
      pins have more than 1 function.
      A19/S6/ONCE , for example, is normally
      an output but functions as an input dur-
      ing
      reset.
      For
      this
      reason
      A19/S6/ONCE is classified as an input/
      output pin.
      Column 3. Input Type (for I and I/O types only)
      There are two different types of input
      pins on the 80C186EC: asynchronous
      and synchronous.
      Asynchronous pins
      require that setup and hold times be met
      only to
      guarantee recognition . Synchro-
      nous input pins require that the setup
      and hold times be met to
      guarantee
      proper operation . Stated simply, missing
      a setup or hold on an asynchronous pin
      will result in something minor (i.e. a timer
      count will be missed) whereas missing a
      setup or hold on a synchronous pin will
      result in system failure (the system will
      ‘‘lock up’’).
      An input pin may also be edge or level
      sensitive.

      have changed, all package prefix variables in this document
      are now indicated with an "x".
