counts (valid bits) roll over from 1 to 0, Timer0 interrupt flag TF0 is set. The timer starts
counting when TCON.4 =1 and either TMOD.3 = 0 or GATE0 = 1. By setting TMOD.3 = 1, the
external input GATE0 can control Timer0 to manage the pulse width measurements. The 13-
bit register consists of 8 bits TH0 and 5 bits of TL0. The upper 3 bits of TL0 should be ignored.
Refer to the following Figure for details.
All of the bits which generate interrupts can be set or cleared by software, with the same
The Timer0 register is configured as a 13-bit register (8bit: Timer, 5bit: prescaler). As the all
