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 behavior of ISP1161A’s DC.
Clearing an IN endpoint buffer causes unpredictable behavior of ISP1161A’s DC.
Reads a copy of the DcStatus register: executing this command does not clear any status bits or interrupt bits.
When accessing an 8-bit register in 16-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.
13.1 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 ISP1161A’s DC and
to perform a device reset.
13.1.1
DcEndpointConfiguration register (R/W: 30H–3FH/20H–2FH)
This command is used to access the DcEndpointConfiguration 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 76
. 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 66
). 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.
