ACKSTALL
ACK SCL Stall
Enables SCL clock stretching during slave-transmit address byte(s) and slave-receiver address and data
byte(s), to allow software to write the Transmit ACK Register before the ACK or NACK is transmitted.
Clock stretching occurs when transmitting the 9th bit, and is therefore not compatible with high speed
mode.
When ACKSTALL is enabled, there is no need to set either RX SCL Stall (SCFGR1[RXSTALL]) or
Address SCL Stall (SCFGR1[ADRSTALL]).
0b - Clock stretching is disabled
1b - Clock stretching is enabled
2
TXDSTALL
TX Data SCL Stall
Enables SCL clock stretching when the Transmit Data flag (SSR[TDF]) is set during a slave-transmit
transfer. Clock stretching occurs following the 9th bit, and is therefore compatible with high speed mode.
0b - Clock stretching is disabled
1b - Clock stretching is enabled
1
RXSTALL
RX SCL Stall
Enables SCL clock stretching when the Receive Data flag (SSR[RDF]) is set during a slave-receive
transfer. Clock stretching occurs following the 9th bit, and is therefore compatible with high speed mode.
0b - Clock stretching is disabled
1b - Clock stretching is enabled
0
ADRSTALL
Address SCL Stall
Enables SCL clock stretching when the Address Valid Flag (SSR[AVF]) is asserted. Clock stretching only
occurs following the 9th bit, and is therefore compatible with high speed mode.
0b - Clock stretching is disabled
1b - Clock stretching is enabled
