(4) Process flow (continuous transmit mode).
Figure 12-29 Timing diagram of the master transmission (continuous transmit mode)
(type 1: DAPmn=0, CKPmn=0)
Note If the BFFmn bit of the serial status register mn (SSRmn) is 1 (when valid data is saved in the serial data register
mn (SDRmn)) is given The SDRmn register writes the transmitted data and overrides the transmitted data.
Note that the MDmn0 bit of the serial mode register mn (SMRmn) can be overridden even during operation. However, in
order to catch up with the end of the transmission interruption of the last transmitted data, it must be overwritten
before the last bit of transmission begins.
Remarks m: Unit number (m=0, 1) n: Channel number (n=0~3) p: SSPI number (p=00, 01, 10, 11, 20, 21.) )
mn=00~03, 10~11
