With N representing the number of bytes, the number of words for 16-bit bus width is: (N + 1) DIV 2.
Validating an OUT endpoint buffer causes unpredictable behaviour of ISP1181.
In 8-bit bus mode this command requires more time to complete than other commands. See
Table 60
.
Clearing an IN endpoint buffer causes unpredictable behaviour of ISP1181.
Reads a copy of the Status Register: executing this command does not clear any status bits or interrupt bits.
In 8-bit mode, the upper byte is invalid.
During isochronous transfer in 16-bit mode, because N
≤
1023, the firmware must take care of the upper byte.
12.1 Initialization commands
Initialization commands are used during the enumeration process of the USB
network. These commands are used to configure and enable the embedded
endpoints. They also serve to set the USB assigned address of ISP1181 and to
perform a device reset.
12.1.1
Write/Read Endpoint Configuration
This command is used to access the Endpoint Configuration Register (ECR) of the
target endpoint. It defines the endpoint type (isochronous or bulk/interrupt), direction
(OUT/IN), FIFO size and buffering scheme. It also enables the endpoint FIFO. The
register bit allocation is shown in
Table 16
. A bus reset will disable all endpoints.
The allocation of FIFO memory only takes place after
all
16 endpoints have been
configured in sequence (from endpoint 0 OUT to endpoint 14). Although the control
endpoints have fixed configurations, they must be included in the initialization
sequence and be configured with their default values (see
Table 4
). Automatic FIFO
allocation starts when endpoint 14 has been configured.
Remark:
If any change is made to an endpoint configuration which affects the
allocated memory (size, enable/disable), the FIFO memory contents of
all
endpoints
becomes invalid. Therefore, all valid data must be removed from enabled endpoints
before changing the configuration.
