10 / 28 page W78958B - 10 - INTERRUPT SOURCE VECTOR ADDRESS PRIORITY SEQUENCE WITHIN LEVEL External Interrupt 0 03H 0 (Highest) Timer/Counter 0 0BH 1 External Interrupt 1 13H 2 Timer/Counter 1 1BH 3 Serial Port 23H 4 Timer/Counter 2 2BH 5 External Interrupt 2 33H 6 External Interrupt 3 3BH 7 (Lowest) Table D7. ESEL Emulation Address Space Select, Input/Output, Dual-purpose TYPE MODE DESCRIPTION Advanced Normal While the W78958B is accessing program memory, ESEL outputs "0." While the W78958B is accessing data memory, the ESEL outputs "1." Emulation Default status is pulled low by internal pull-high resistor. ESEL is used to select two emulation address spaces. When ESEL is held in "L" state, the SFR/PC and internal RAM can be accessed, and AP7<0>(EWR) and AP7<1>(ERD) are the active low write and read control input signals, respectively. When ESEL is held in "H" state, the external ROM and RAM can be accessed (P3.6 and P3.7 are weakly pulled high by internal pull-high resistors). Standard Normal Same as in the advanced type. Emulation Default status is pulled low by internal pull-high resistor. ESEL is used to select two emulation address spaces. When ESEL is held in "L" state, the SFR/PC and internal RAM can be accessed, and AP7<0>(EWR) and AP7<1>(ERD) are the active low write and read control input signals, respectively. When ESEL is held in "H" state, the external ROM/RAM can be accessed (P3.6/P3.7 are weakly pulled high by internal pull-high resistors), P0.7 −P0.0 are floating, and P2.7 −P2.0 are in high impedance state optionally dependent on the content of register MP2. |
