• Manufacturer Part Number: zic2410
• Description: Single-chip Solution, Compliant With Zigbee
• Manufacturer: California Eastern Laboratories

If the time-out period is set too short, excessive interrupts will occur causing abnormal operation
of the system. It is recommended to set a sufficient time-out period for Timer3.
PWM 2/3
TIMER 2/3 can be used as Pulse Width Modulators, PWM2 and PWM3 respectively based on
setting the M2, M3 bits in T23CON register. P 3.6 outputs PWM2 signal and P3.7 outputs
PWM3 signal
The following table describes the frequency and High Level Duty Rate in PWM mode.
Rev A
Note: This equation does not apply for TH values of 0, and 1. For these values the frequency should be as
follows: TH=0: 15.625 KHz; TH=1: 7.812 KHz.
