CHAPTER 16 I C INTERFACE
[bit11] ACK (ACKnowledge)
This bit generates an acknowledge according to the setting of the data receive enable bit.
0
1
This bit is disabled when slave address data is received in slave mode.
An acknowledge is returned if the I
corresponding enable bits (ENTB: ITMK, ENSB: ISMK) are set.
Write to this bit while an interrupt flag is set (INT=1), the bus is idle (BB=0: IBSR), or the I
interface is stopped (EN=0: ICCR).
[bit10] GCAA (General Call Address Acknowledge)
This bit is an acknowledge enable bit used when a general call address is received.
0
1
Write to this bit while an interrupt flag is set (INT=1), the bus is idle (BB=0: IBSR), or the I
interface is stopped (EN=0: ICCR).
[bit9] INTE (INTerrupt Enable)
This bit is the interrupt enable bit.
0
1
When this bit is "1", the interrupt is generated if the INT bit is "1".
[bit8] INT (INTerrupt)
This bit is the transfer end interrupt request flag bit. For a read by a read modify instruction,
"1" is always read.
