Register Description - TWI
Register Description - TWI Master
CTRL– TWI Common Control Register
CTRLA - TWI Master Control Register A
• Bit 7:2 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 1
SCL.
• Bit 0 - EDIEN: External Driver Interface Enable
Setting this bit enables the use of the external driver interface, clearing this bit enables normal
two wire mode. See
Table 19-1.
• Bit 7:6 - INTLVL[1:0]: Interrupt Level
The Interrupt Level (INTLVL) bit select the interrupt level for the TWI master interrupts.
• Bit 5 - RIEN: Read Interrupt Enable
Setting the Read Interrupt Enable (RIEN) bit enables the Read Interrupt when the Read Interrupt
Flag (RIF) in the STATUS register is set. In addition the INTLVL bits must be unequal zero for
TWI master interrupts to be generated.
Setting this bit to one enables an internal hold time on SDA with respect to the negative edge of
