Note:
This “two-tiered” interrupt enabling/disabling approach, for the “Input Change of State” interrupt allows tremendous flexibility for the
user. Setting or clearing the bits in ACR[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 IMR[7] allows the user to “globally” enable or disable this
interrupt.
