Notes
1. Pin type abbreviations: I = Input, O = Output and S = Supply.
2. Used in NEC V851 and 16-bit Intel 8031 microcontroller interface configurations.
3. DMA data to the external buffer manager may be configured for 16 or 8 bits wide. For 16-bit operation pins
DMA_DATA[15:0] are used, and for 8-bit operation, pins DMA_DATA[7:0] are used.
4. For more information see IEEE1394-1995 standard, Annex J.
5. Data is expected on PHY_DATA[0:1] for 100 Mbits/s, PHY_DATA[0:3] for 200 Mbits/s and PHY_DATA[0:7] for
400 Mbits/s.
6. To preserve compatibility to the specified Link-PHY interface of the IEEE1394-1995 standard, Annex J, bit 0 is the
most significant bit.
7. During Power-on reset, this line is sampled to select between IEEE1394-1995 mode (HIGH) and P1394a mode
(LOW). A 22 k
pull-up or pull-down resistor should be connected accordingly. This line acts as the MICRO_WAIT
line when the V851 microcontroller interface mode is selected.
8. Used in NEC V851 and Intel 8031 (8-bit and 16-bit) microcontroller interface configurations.
9. This is the data bus for all microcontroller interface configurations. This forms the lower address bus for the
NEC V851 and Intel 8031 microcontroller configurations.
10. MICRO_SEL [1:0] = ‘00’ selects 8-bit 8031 mode; MICRO_SEL [1:0] = ‘01’ selects H8 mode;
MICRO_SEL [1:0] = ‘10’ selects 16-bit 8031 mode; MICRO_SEL [1:0] = ‘11’ V851 mode.
