MPEG bus out of PACE 2200 (all signals are box to card)
- coclk
- Clock, other signals should be sampled at rising edge of it.
- costart
- High for first byte of every 188-byte transport stream packet (the $47 byte)
- covalid
- High if byte is transferred this clock cycle. Low if no transfer.
- co1394[]
- Data byte. 7 is MSB, 0 is LSB.
- conoterror
- Normally high, low if error detected upstream (eg ECC uncorrectable detcted)
MPEG bus into PACE 2200 (all signals are card to box)
- ciclk
- Clock, box will use rising edge to sample other signals.
- cistart
- High for first byte of every 188-byte transport stream packet (the $47 byte)
- civalid
- High if byte is transferred this clock cycle. Low if no transfer.
- ci1394[]
- Data byte. 7 is MSB, 0 is LSB.
- cinoterror
- Normally high, low if error detected by card
ST20 processor bus signals
- not1394_cs
- Chip select from ST20 processor to card
- notsyswr
- ST20 processor write strobe to card
- notsysrd
- ST20 processor read strobe to card
- memaddr[]
- Part of the address bus of the ST20 processor to card
- memdata[]
- Part of the data bus of the ST20 processor, bidi
- notwait1394
- Pulled low to extend ST20 cycles for slow cards
- not1394_irq
- Interrupt from card?
Other signals
- notcd1,notcd2
- These are usually connected to GND on the card, and are sensed by the box to know
when a card is present. By grounding via a transistor, one can dynamically switch presence.
- not1394_rst
- Reset to card?
- extsda,extscl
- I2C bus to card. Possibly for an I2C eeprom?
- not_module_uses_i2c
- Presumably tied low if I2C used by this card?
- +5V
- 5V power supply, limited current available for card use!
- +3.3V
- 3.3V power supply, limited current available for card use!
