MASTER1 SMBus1 Master/Slave

Indicator. This read-only bit

indicates when the SMBus1 is

operating as a master.

TXMODE1 SMBus1 Transmit Mode

Indicator. This read-only bit

indicates when the SMBus1 is

operating as a transmitter.

0: SMBus1 operating in

slave mode.

1: SMBus1 operating in

master mode.

0: SMBus1 in Receiver

Mode.

1: SMBus1 in Transmitter

Mode.

STA1

SMBus1 Start Flag.

0: No Start or repeated

0: No Start generated.

Start detected.

1: Start or repeated Start

detected.

1: When Configured as a

Master, initiates a START

or repeated START.

4

STO1

SMBus1 Stop Flag.

0: No Stop condition

0: No STOP condition is

detected.

1: Stop condition detected

(if in Slave Mode) or

pending (if in Master

Mode).

transmitted.

1: When configured as a

Master, causes a STOP

condition to be transmit-

ted after the next ACK

cycle.

Cleared by Hardware.

ACK1

SMBus1 Acknowledge.

0: NACK received.

0: Send NACK

SI1

SMBus1 Interrupt Flag.

This bit is set by hardware

under the conditions listed in

Table 15.3. SI1 must be

0: No interrupt pending

1: Interrupt Pending

0: Clear interrupt, and ini-

tiate next state machine

event.

1: Force interrupt.

cleared by software. While SI1

is set, SCL1 is held low and

the SMBus1 is stalled.
