Note:
approach, for the “Input Change of State” interrupt allows
tremendous flexibility for the user. Setting or clearing the
bits in ACR1[3:0] and/or ACR2[3:0] allows the user to
specify exactly which Input Port pins to be enabled (or
disabled) for generating the “Input Port Change of State”
interrupt. Setting or clearing IMR1[7] and/or IMR2[7]
allows the user to “globally” enable or disable this
interrupt.
