I2C MSTCTL addressOffset = 0x020

The MSTCTL register contains bits that control various functions of the I^ 2C Master interface. Only write to this register when the master is pending (MSTPENDING = 1 in the STAT register, I2C registerName = STAT addressOffset = 0x004).

Table 1. I2C registerName = MSTCTL addressOffset = 0x020
Bit Symbol Value Description Reset value
0 MSTCONTINUE   Master Continue. This bit is write-only. 0
    0 No effect.  
    1 Continue. Informs the Master function to continue to the next operation. This must be done after writing transmit data, reading received data, or any other housekeeping related to the next bus operation.  
1 MSTSTART   Master Start control. This bit is write-only. 0
    0 No effect.  
    1 Start. A Start will be generated on the I^ 2C bus at the next allowed time.  
2 MSTSTOP   Master Stop control. This bit is write-only. 0
    0 No effect.  
    1 Stop. A Stop will be generated on the I^ 2C bus at the next allowed time, preceded by a NACK to the slave if the master is receiving data from the slave (Master Receiver mode).  
31:2 -   Reserved. Read value is undefined, only zero should be written. NA
