Attention should be paid to the following three modes
having special circuits:
INTO Level mode
IF INTO is not an edge-based interrupt, the function of Interrupt Request Flip-flop is cancelled. Therefore, the interrupt request signal must be
held until the interrupt request is acknowledged by the CPU. A change in the mode (edge to level) automatically clears the interrupt request
flag.
When the CPU has been put in the interrupt response sequence with INT0 level mode, it is necessary to leave INT0 at “1” until the second
bus cycle of the interrupt response sequence is completed. Also, “1” must always be held until HALT is cleared when using the INT0 level
mode to clear HALT. (Use care to prevent noise changing “1” back to “0”.)
When switching from the level mode to the edge mode, the interrupt request flag set in the level mode is not cleared; therefore, use the fol-
lowing sequence to clear the interrupt request flag.
DI
LD (0FF9FH), 01H: switch from level to edge
LD (0FF9EH), 04H: clear interrupt request flag
EI
INTRX level mode
The Interrupt Request Flip-flop is cleared only by resetting or reading the serial channel receiving buffer, and not by an instruction.
