Pin type abbreviations: I = Input, O = Output and S = Supply.
Used in NEC V851 and 16-bit Intel 8031 microcontroller interface configurations.
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.
For more information see IEEE1394-1995 standard, Annex J.
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.
To preserve compatibility to the specified Link-PHY interface of the IEEE1394-1995 standard, Annex J, bit 0 is the
most significant bit.
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.
Used in NEC V851 and Intel 8031 (8-bit and 16-bit) microcontroller interface configurations.
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.
