a serial transfer completion interrupt request only when it receives an address.
subsequent command or data reception.
17.5.4 SBI Mode Control Registers
(1) Clocked serial interface mode register (CSIM)
In SBI communication, a specific slave device is selected and communication is started by master address transmission.
Slave device address match detection is performed by software. In the wake-up state (WUP = 1), a slave generates
In match address reception processing by software, the wake-up state is released (WUP
The CSIM is an 8-bit register that specifies the serial interface operating mode, serial clock, wake-up function, etc.
The format of the CSIM is shown in Figure 17-11.
CSIM can be read or written to with an 8-bit manipulation instruction or bit manipulation instruction, but read/write
attributes are assigned bit by bit.
RESET input clears the value of CSIM to 00H.
