5.3.3 Register Description
The PWM is associated with a 8-bit control regis-
ters, and with two 16-bit data registers, each split
in two 8-bit registers.
PWM CYCLE REGISTER LOW (CYREGL)
PWM1 Register Address: 0011h
PWM2 Register Address: 0019h
Read/Write
Reset Value: 0000 0000 (00h)
This is an 8-bit register that contains the low part of
the value to be multiplied by internal clock period.
PWM CYCLE REGISTER HIGH (CYREGH)
PWM1 Register Address: 0010h
PWM2 Register Address: 0018h
Read/Write
Reset Value: 0000 0000 (00h)
This is an 8-bit register that contains the high part
of the value to be multiplied by internal clock peri-
od.
PWM DUTYCYCLE REGISTER LOW (DU-
TYREGL)
PWM1 Register Address: 0013h
PWM2 Register Address: 001Bh
Read/Write
Reset Value: 0000 0000 (00h)
This is an 8-bit register that contains the low part
of the value corresponding to the binary weight of
the PWM pulse.
PWM DUTYCYCLE REGISTER HIGH (DU-
TYREGH)
PWM1 Register Address: 0012h
PWM2 Register Address: 001Ah
Read/Write
Reset Value: 0000 0000 (00h)
This is an 8-bit register that contains the high part
of the value corresponding to the binary weight of
the PWM pulse
.
PWM CONTROL REGISTER (CONREG)
PWM1 Register Address: 0014h
PWM2 Register Address: 001Ch
Read/Write
Reset Value: 0000 0000 (00h)
Bit 0=
EN _PWM
: 1 = enables the PWM output, 0
= disables PWM output.
Bit 1=
EN _INT
: 1 = enables interrupt request, 0
disables interrupt request.
Bit 4, 3, 2=
PS2
,
PS1
,
PS0
: prescaler bits
The value of the PWM internal clock depends on
these bits.
Bit 5, 6, 7= not used.
