Chapter 11 PWM
11 – 11
11.4.2 Functioning P34 (PWM0) as the PWM output
Set P34MD1 bit (bit4 of P3MOD1 register) to “1” and set P34MD0 bit (bit4 of P3MOD0 register) to “0”, for
specifying the PWM output as the tertiary function of P34.
Reg. name P3MOD1 register (Address: 0F21DH)
Bit 7 6 5 4 3 2 1 0
Bit name
- - P35MD1 P34MD1 P33MD1 P32MD1 P31MD1 P30MD1

Set P34C1 bit (bit4 of P3CON1 register) to “1”, set P34C0 bit(bit4 of P3CON0 register) to “1” and set P34DIR
bit(bit4 of P3DIR register) to “0”, for specifying the P34 as CMOS output.
Reg. name P3CON1 register (Address: 0F21BH)
Bit 7 6 5 4 3 2 1 0

Data - - * 0 * * * *
Data of P34D bit (bit4 of P3D register) does not affect to the PWM output function, so don’t care the data for the
function.
Reg. name P3D register (Address: 0F218H)
Bit 7 6 5 4 3 2 1 0
Bit name
- - P35D P34D P33D P32D P31D P30D
Data - - * ** * * * *
- : Bit does not exist.
* : Bit not related to the PWM function
** : Don’t care the data.
