Bits 1 and 0: Clock select 1 and 0 (PWCR1, PWCR0)
Bits 1 and 0 select the clock supplied to the 14-bit PWM. These bits are write-only bits; they are
always read as 1.
Bit 1
PWCR1
Bit 0
PWCR0 Description
0 0 The input clock is φ/2 (tφ
*
= 2/φ)
The conversion period is 16,384/φ, with a minimum modulation
width of 1/φ
(initial value)
0 1 The input clock is φ/4 (tφ
*
= 4/φ)
The conversion period is 32,768/φ, with a minimum modulation
width of 2/φ
1 0 The input clock is φ/8 (tφ
*
= 8/φ)
The conversion period is 65,536/φ, with a minimum modulation
width of 4/φ
1 1 The input clock is φ/16 (tφ
*
= 16/φ)
The conversion period is 131,072/φ, with a minimum
modulation width of 8/φ
Note: * Period of PWM input clock.
