Description
Asynchronous Mode Clock Source Select (valid when
CKE1 = 1 in asynchronous mode)
These bits select the clock source for the average
transfer rate function. When the average transfer rate
function is enabled, the base clock is automatically
specified regardless of the ABCS bit value.
000: External clock input
001: 115.192 kbps of average transfer rate specific to
010: 460.784 kbps of average transfer rate specific to

111: 720 kbps of average transfer rate specific to Pφ =
The average transfer rate only supports operating
frequencies of 10.667 MHz, 16 MHz, and 32 MHz.
Section 14 Serial Communication Interface (SCI, IrDA, CRC)
Pφ = 10.667 MHz is selected (operated using the
base clock with a frequency 16 times the transfer
rate)
Pφ = 10.667 MHz is selected (operated using the
base clock with a frequency 8 times the transfer
rate)
32 MHz is selected (operated using the base clock
with a frequency 16 times the transfer rate)
Pφ = 16 MHz is selected (operated using the base
clock with a frequency 16 times the transfer rate)
Pφ = 16 MHz is selected (operated using the base
clock with a frequency 16 times the transfer rate)
16 MHz is selected (operated using the base clock
with a frequency 8 times the transfer rate)
