AT90PWM81
• Bits 3:0 – CSEL3:0: Clock Source Select
CSEL bits are initialized with the values of CKSEL Fuse bits.
In case of ‘Enable/Disable Clock Source’, ‘Request for Clock Availability’ or ‘Clock Source Switch’
command, CSEL field gets back the code of the clock source. Refer to
Table 5-1 on page 28
and subdivi-
sions of
Section 5.2 ”Clock Sources” on page 28
for clock source codes.
In case of ‘Recover System Clock Source’ command, CSEL field receives the code of the clock source
used to drive the Clock Control Unit as described in
Figure 5-1 on page
27.
