GENERAL RELEASE SPECIFICATION
PRELMNARY
Bit 6
The No AcKnowledge Interrupt Flag is only set in master
mode when there is no acknowledge bit detected after one
data byte or calling address is transferred. This bit can
generate an interrupt request to cpu when the DIEN bit in
DCR register is set and I-bit in the Condition Code Register is
clear. This bit is cleared by writing ’0’ to it or by reset.
Bit 5
The Bus Busy Flag is set after a start condition is detected,
and is reset when a stop condition is detected. This bit can
supplement the software in initiating the master mode
protocol. Reset clears this bit.
TXAK
Bit 3
If the transmit acknowledge enable bit (TXAK) is cleared, an
acknowledge signal will be sent out to the bus at the 9th clock
bit after receiving 8 data bits. When TXAK is set, no
acknowledge signal will be generated at the 9th clock (i.e.,
acknowledge bit = 1). Reset clears this bit.
If the SCL Interrupt ENable bit (SCLIEN) is set, the interrupt
occurs provided the SCLIF in the status register is set and the
I-bit in the Condition Code Register is cleared. If SCLIEN is
cleared, the interrupt of SCLIF is disabled. Reset clears this
bit.
When DDC1 protocol ENable (DDC1EN) is set, the VSYNC
edge will continuously clock out the data in the shift register.
No calling address comparison is performed. The RW bit in
the status register will be fixed to be one. If this bit is clear, the
SCLIF bit in the status register is also cleared. Reset clears
this bit.
SCLIEN
Bit 2
DDC1EN
Bit 1
9.3.3
DDC Master Control Register (DMCR)
The DMCR contains two interrupt flags, one bus status flag, two master mode control bits,
and three baudrate select bits.
ALIF
Bit 7
The Arbitration Loss Interrupt Flag is set when software
attempt to set MAST but the BB has been set by detecting the
start condition on the lines or when the DDC12AB module is
transmitting a ’one’ to SDA line but detected a ’zero’ from SDA
line in master mode, which is so called arbitration loss. This
bit can generate an interrupt request to cpu when the DIEN bit
in DCR register is set and I-bit in the Condition Code Register
