# Edge Triggered Hardware Limit Mode

In Hardware Limit mode, the timer can be reset by the TMRx_ers external signal before the timer reaches the period count. Three types of Resets are possible:

• Reset on rising or falling edge (MODE = ‘b00011)
• Reset on rising edge (MODE = ‘b00100)
• Reset on falling edge (MODE = ‘b00101)

When the timer is used in conjunction with the CCP in PWM mode then an early Reset shortens the period and restarts the PWM pulse after a two clock delay. Refer to Figure 1.
