These settings are ignored in Auto Setting Mode. Refer Table 22.
This setting is ignored in Auto Setting Mode. Refer Table 21.
0: Disable, Manual Setting Mode (default)
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKSB bit “1”. In this case, the setting of
DFSAD, DFSDA1-0 bits of the block connecting this PORT is ignored. When this bit is “0”,
DFSAD, DFSDA1-0 bits set the sampling speed mode.
0: Disable, Manual Setting Mode (default)
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKSAO bit “1”. In this case, the setting of
DFSAD, DFSDA1-0 bits of the block connecting this PORT is ignored. When this bit is “0”,
DFSAD, DFSDA1-0 bits set the sampling speed mode.
0: Disable, Manual Setting Mode (default)
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKSAI bit “1”. In this case, the setting of
DFSAD, DFSDA1-0 bits of the block connecting this PORT is ignored. When this bit is “0”,
DFSAD, DFSDA1-0 bits set the sampling speed mode.
