With N representing the number of bytes, the number of words for 16-bit bus width is: (N + 1)/2.
Validating an OUT endpoint buffer causes unpredictable behavior of the ISP1161A1’s DC.
Clearing an IN endpoint buffer causes unpredictable behavior of the ISP1161A1’s DC.
Reads a copy of the Status 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.

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 the ISP1161A1’s DC
and to perform a device reset.
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
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
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.
