Figure 14 - 30 Timing Chart of Master Transmission (in Continuous Transmission Mode)
(Type 1: DAPmn = 0, CKPmn = 0)
Note
If transmit data is written to the SDRmn register while the BFFmn bit of serial status register mn (SSRmn) is 1 (valid data
is stored in serial data register mn (SDRmn)), the transmit data is overwritten.
Caution The MDmn0 bit of serial mode register mn (SMRmn) can be rewritten even during operation.
However, rewrite it before transfer of the last bit is started, so that it will be rewritten before the transfer end
interrupt of the last transmit data.
