Table 43: The IRCON Bit Functions
Note: Only TF0 and TF1 (timer 0 and timer 1 overflow flag) will be automatically cleared by hardware when the service routine
is called (Signals T0ACK and T1ACK – port ISR – active high when the service routine is called).
External Interrupts
The external interrupts are connected as shown in Table 44. The polarity of interrupts 2 and 3 is programmable in the MPU.
Interrupts 2 and 3 should be programmed for falling sensitivity. The generic 8051 MPU literature states that interrupts 4
through 6 are defined as rising edge sensitive. Thus, the hardware signals attached to interrupts 5 and 6 are inverted to
achieve the edge polarity shown in Table 44.
SFR (special function register) enable bits must be set to permit any of these interrupts to occur. Likewise, each interrupt has
its own flag bit that is set by the interrupt hardware and is reset automatically by the MPU interrupt handler (0 through 5).
