Description
Asynchronous clock source selection (valid when
CKE1 = 1 in asynchronous mode)
Selects the clock source for the average transfer
rate.
The basic clock can be automatically set by
selecting the average transfer rate in spite of the
value of ABCS.
000: External clock input
001: Selects 115.152 kbps which is the average
010: Selects 460.606 kbps which is the average
011: Selects 720 kbps which is the average
100: Reserved
101: Selects 115.196 kbps which is the average
110: Selects 460.784 kbps which is the average
111: Selects 720 kbps which is the average
Note that the average transfer rate does not
correspond to the frequency other than 10.667,
16, or 32 MHz.
transfer rate dedicated for φ= 10.667 MHz.
(Operates on a basic clock with a frequency
of 16 times the transfer rate.)
transfer rate dedicated for φ= 10.667 MHz.
(Operates on a basic clock with a frequency
of 8 times the transfer rate.)
transfer rate dedicated for φ = 32 MHz.
(Operates on a basic clock with a frequency
of 16 times the transfer rate.)
transfer rate dedicated for φ = 16 MHz
(Operates on a basic clock with a frequency
of 16 times the transfer rate.)
transfer rate dedicated for φ = 16 MHz
(Operates on a basic clock with a frequency
of 16 times the transfer rate.)
transfer rate dedicated for φ = 16 MHz
