Control transaction limitations
The different phases of a Control transfer (SETUP, Data and Status) should never be
put in the same ATL.
9.6 Microprocessor loading
The maximum amount of data that can be transferred for an endpoint in one frame is
1023 bytes. The number of USB packets that are needed for this batch of data
depends on the maximum packet size that is specied.
The HCD has to schedule the transactions in a frame. On the other hand, the
microprocessor must have the ability to handle the interrupts coming from the HC
every 1 ms. It must also be able to do the scheduling for the next frame, reading the
frame information from and writing the next frame information to the buffer RAM in the
time between the end of the current frame and the start of the next frame.
9.7 Internal pull-down resistors for downstream ports
There are four internal 15 k
pull-down resistors built in the ISP1160 for the two
downstream ports: two resistors for each port. These resistors are software
selectable by programming bit 12 (2_DownstreamPort15Kresistorsel) of the
HcHardwareConguration register (20H to read, A0H to write). When bit 12 is logic 0,
external 15 k
pull-down resistors are used. When bit 12 is logic 1, internal 15 k
pull-down resistors are used. See Figure 24.
This feature is a cost-saving option. However, the power-on reset default value of
bit 12 is logic 0. If using the internal resistors, the HCD must check this bit status after
every reset, because a reset action (hardware or software) will clear this bit.
