Preliminary specification
1394 SBP-2 link layer controller
SAA7356HL
7.4.2
H
ITACHI
H8
INTERFACE
In this mode, the address and data buses are
non-multiplexed. The address bus is connected directly to
the MICRO_ADDR pins and the data bus is connected
directly onto the MICRO_DATA pins.
TheMICRO_CSpinmustbeassertedbeforetheassertion
of the MICRO_READ pin. The SAA7356HL will stop
driving the microcontroller data bus when either the
MICRO_CS pin or the MICRO_READ pin are negated.
The H8 microcontroller supports wait states. The timing is
shown in Fig.6. Note that the MICRO_WAIT pin must be
low during the falling edge of the (H8) CLK during state T2.
Since the relationship between the SAA7356HL and the
H8 clock is unknown the MICRO_WAIT pin is asserted low
when the MICRO_READ and the MICRO_CS are
asserted. The SAA7356HL will de-assert the
MICRO_WAIT line once the data is ready for transfer.
7.4.3
NEC V851
INTERFACE SUPPORT
The most important timing information for this
microcontroller is given in Fig.7.
The MICRO_WAIT line must be low during the falling edge
of the (V851) CLK during state T2: this is the same
requirement as the H8. Instead of a MICRO_READ and a
MICRO_WRITE signal the V851 uses a R/W and DSTB
signal. The address lines are time multiplexed and should
be latched using the ASTB signal.
7.5
Interrupt handling
The SAA7356HL may use interrupts to communicate with
the microcontroller. The microcontroller will read from the
CmdToMicro
register to find the interrupt reason.
If parameters are required with the command then this is
implied in the command byte.These parameters may then
be read from the SAA7356HL RAM using the
RAM.Offset
and the
RAM.Next
registers.
7.6
Address map for the SAA7356HL
The address mapping for the 4-bit, 8-bit and 16-bit
addressing modes is given in Table 1.
