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 sets IE0 in the TCON register. If bit IT0 in this register is set,
bit IE0 is set by a falling edge on INT0#. If bit IT0 is cleared, bit IE0 is
set by a low level on INT0#.
Timer 1 Gate Input
INT1 serves as external run control for timer 1, when selected by
GATE1 bit in TCON register.
External Interrupt 1
INT1 input sets IE1 in the TCON register. If bit IT1 in this register is set,
bit IE1 is set by a falling edge on INT1#. If bit IT1 is cleared, bit IE1 is
set by a low level on INT1#.
Timer 0 External Clock Input
When timer 0 operates as a counter, a falling edge on the T0 pin
increments the count.
Timer 1 External Clock Input
When timer 1 operates as a counter, a falling edge on the T1 pin
increments the count.
