These bits select the SCIF clock source and whether to
enable or disable the clock output from the SCIF_SCK
pin. The CKE1 and CKE0 bits are used together to
specify whether the SCIF_SCK pin functions as a serial
clock output pin or a serial clock input pin. Note
however that the CKE0 bit setting is valid only when an
internal clock is selected as the SCIF clock source
(CKE1 = 0). When an external clock is selected (CKE1
= 1), the CKE0 bit setting is invalid. The CKE1 and
CKE0 bits must be set before determining the SCIF's
operating mode with SCSMR.
•
Asynchronous mode
00: Internal clock/SCIF_SCK pin functions as port by
setting SCSPTR register
01: Internal clock/SCIF_SCK pin functions as clock
output
*
1
1x: External clock/SCIF_SCK pin functions as clock
input
*
2
•
Clocked synchronous mode
0x: Internal clock/SCIF_SCK pin functions as
synchronization clock output
1x: External clock/SCIF_SCK pin functions as
synchronization clock input
Notes: x: Don't care
1. Outputs a clock with a frequency 16 times the
bit rate.
2. Inputs a clock with a frequency 16 times the
bit rate.
