Description
Timer 0 Gate Input
INT0 serves as external run control for timer 0, when selected by GATE0
bit in TCON register.
External Interrupt 0
INT0 input set IE0 in the TCON register. If bit IT0 in this register is set, bits
IE0 are set by a falling edge on INT0. If bit IT0 is cleared, bits IE0 is set by
bit in TCON register.
External Interrupt 1
INT1 input set IE1 in the TCON register. If bit IT1 in this register is set, bits
IE1 are set by a falling edge on INT1. If bit IT1 is cleared, bits IE1 is set by
Timer/Counter 2 Reload/Capture/Direction Control Input
a low level on INT0.
Timer 1 Gate Input
INT1 serves as external run control for Timer 1, when selected by GATE1
a low level on INT1.
Timer Counter 0 External Clock Input
When Timer 0 operates as a counter, a falling edge on the T0 pin
increments the count.
Timer/Counter 1 External Clock Input
When Timer 1 operates as a counter, a falling edge on the T1 pin
increments the count.
Timer/Counter 2 External Clock Input
Timer/Counter 2 Clock Output
