The Continue/Busy bit is cleared by hardware prior to interrupt conditions 1 to 4. Once the Data Register has been read or written,
firmware should configure the other control bits and set the Continue/Busy bit for subsequent transactions. Following an interrupt
from master mode, firmware should perform only one write to the Status and Control Register that sets the Continue/Busy bit,
without checking the value of the Continue/Busy bit. The Busy bit may otherwise be active and I
changed by the hardware during the transaction, until the I

The USB hardware includes a USB Hub repeater with one upstream and up to seven downstream ports. The USB Hub repeater
interfaces to the microcontroller through a full-speed serial interface engine (SIE). An external series resistor of R
placed in series with all upstream and downstream USB outputs in order to meet the USB driver requirements of the USB
specification. The CY7C65113C microcontroller can provide the functionality of a compound device consisting of a USB hub and
permanently attached functions.
15.1
The SIE allows the CY7C65113C microcontroller to communicate with the USB host through the USB repeater portion of the hub.
The SIE simplifies the interface between the microcontroller and USB by incorporating hardware that handles the following USB
bus activity independently of the microcontroller:
Firmware is required to handle the following USB interface tasks:
15.2
The internal hub and any compound device function are enumerated under firmware control. The hub is enumerated first, followed
by any integrated compound function. After the hub is enumerated, the USB host can read hub connection status to determine
which (if any) of the downstream ports need to be enumerated. The following is a brief summary of the typical enumeration
process of the CY7C65113C by the USB host. For a detailed description of the enumeration process, refer to the USB specifi-
cation.
In this description, ‘Firmware’ refers to embedded firmware in the CY7C65113C controller.
3. In slave transmit mode, after the slave transmits a byte of data: The ACK bit indicates if the master that requested the byte
4. In master transmit mode, after the master sends a byte of data. Firmware should load the Data Register if necessary, and
5. In master receive mode, after the master receives a byte of data: Firmware should read the data and set the ACK and
6. When the master loses arbitration: This condition clears the MSTR MODE bit and sets the ARB Lost/Restart bit immediately
1. The host computer sends a SETUP packet followed by a DATA packet to USB address 0 requesting the Device descriptor.
2. Firmware decodes the request and retrieves its Device descriptor from the program memory tables.
3. The host computer performs a control read sequence and Firmware responds by sending the Device descriptor over the USB
4. After receiving the descriptor, the host sends a SETUP packet followed by a DATA packet to address 0 assigning a new USB
5. Firmware stores the new address in its USB Device Address Register (for example, as Address B) after the no-data control
