Bit 4
CKP:
SCL Clock Priority Control bit
In MSP Slave mode
0 = Hold SCL keeping Low. (Ensure data setup time and Slave device ready.)
1 = Release SCL Clock
(Slave Transistor mode CKP function always enables, Slave Receiver CPK function control by SLRXCKP)
In MSP Master mode Unused.
Bit 3
SLRXCKP:
Slave Receiver mode SCL Clock Priority Control bit
In MSP Slave Receiver mode.
0 = Disable CKP function.
1 = Enable CKP function.
In MSP Slave and Slave Transistor mode Unused.
Bit 2
MSPWK:
MSP Wake-up indication bit
0 = MCU NOT wake-up by MSP.
1 = MCU wake-up by MSP
Note1. Clear MSPWK before entering Power down mode for indication the wake-up source from MSP or
not
Bit 0
MSPC:
MSP mode Control register
0 = MSP operated on Slave mode, 7-bit address
1 = MSP operated on Master mode.
Note1.If MSP want to operated on Master mode,MSPC must be setting 1 after MSPENB.
Ex:b0bset MSPENB
