SI
Serial Interrupt ag. This ag is set and an interrupt request is generated, after
any of the following events occur:
A START condition is generated in master mode
The own slave address has been received during AA = 1
The general call address has been received while S1ADR.GC and AA = 1
A data byte has been received or transmitted in master mode (even if arbitration
is lost)
A data byte has been received or transmitted as selected slave
A STOP or START condition is received as selected slave receiver or
transmitter. While the SI ag is set, SCL remains LOW and the serial transfer is
suspended. SI must be reset by software.
AA
Assert Acknowledge ag. When this bit is set, an acknowledge is returned
after any one of the following conditions:
Own slave address is received
General call address is received (S1ADR.GC = 1)
A data byte is received, while the device is programmed to be a master receiver
A data byte is received, while the device is selected slave receiver.
When the bit is reset, no acknowledge is returned. Consequently, no interrupt is
requested when the own address or general call address is received.
I2C-bus Data Register (S1DAT)
DAT7 to DAT0
I2C-bus data
I2C-bus Status Register (S1STA)
STAT4 to STAT0
I2C-bus interface status
Software ADC Register (SAD)
VHI
analog input voltage greater than DAC voltage (logic 1)
CH1 to CH0
ADC input channel select bits; CH<1:0>:
00 = ADC3
01 = ADC0
10 = ADC1
11 = ADC2
ST(1)
initiate voltage comparison between ADC input channel and SAD value
SAD7 to SAD4
4 MSBs of DAC input word
Software ADC Control Register (SADB)
DC_COMP
enable DC comparator mode (logic 1)
SAD3 to SAD0
4 LSBs of SAD value
Stack Pointer (SP)
SP7 to SP0
stack pointer value
BIT
