Table 2.
The ‘last bit of the instruction’ can be the eighth bit of the instruction code, or the eighth
bit of a data byte, depending on the instruction (except for Read Status Register
(RDSR) and Read (READ) instructions).
The ‘next rising edge of Serial Clock (C)’ might (or might not) be the next bus
transaction for some other device on the SPI bus.
