49 Tip: To avoid modifying these defines each time you need to change the USB
50 configuration, you can declare the needed define in your toolchain
51 compiler preprocessor.
53 /****************** USB OTG FS PHY CONFIGURATION *******************************
54 * The USB OTG FS Core supports one on-chip Full Speed PHY.
56 * The USE_EMBEDDED_PHY symbol is defined in the project compiler preprocessor
57 * when FS core is used.

67 /****************** USB OTG HS PHY CONFIGURATION *******************************
68 * The USB OTG HS Core supports two PHY interfaces:
69 * (i) An ULPI interface for the external High Speed PHY: the USB HS Core will
70 * operate in High speed mode
71 * (ii) An on-chip Full Speed PHY: the USB HS Core will operate in Full speed mode
73 * You can select the PHY to be used using one of these two defines:
74 * (i) USE_ULPI_PHY: if the USB OTG HS Core is to be used in High speed mode
75 * (ii) USE_EMBEDDED_PHY: if the USB OTG HS Core is to be used in Full speed mode
78 * - The USE_ULPI_PHY symbol is defined in the project compiler preprocessor as
79 * default PHY when HS core is used.
80 * - On STM322xG-EVAL and STM324xG-EVAL boards, only configuration(i) is available.
81 * Configuration (ii) need a different hardware, for more details refer to your
82 * STM32 device datasheet.

101 * FIFO Size Configuration in Device mode
103 * (i) Receive data FIFO size = RAM for setup packets +
104 * OUT endpoint control information +
105 * data OUT packets + miscellaneous
106 * Space = ONE 32-bits words
107 * --> RAM for setup packets = 10 spaces
108 * (n is the nbr of CTRL EPs the device core supports)
109 * --> OUT EP CTRL info = 1 space
110 * (one space for status information written to the FIFO along with each
112 * --> data OUT packets = (Largest Packet Size / 4) + 1 spaces
113 * (MINIMUM to receive packets)
114 * --> OR data OUT packets = at least 2*(Largest Packet Size / 4) + 1 spaces
115 * (if high-bandwidth EP is enabled or multiple isochronous EPs)
116 * --> miscellaneous = 1 space per OUT EP
117 * (one space for transfer complete status information also pushed to the
118 * FIFO with each endpoint's last packet)
120 * (ii)MINIMUM RAM space required for each IN EP Tx FIFO = MAX packet size for
121 * that particular IN EP. More space allocated in the IN EP Tx FIFO results
122 * in a better performance on the USB and can hide latencies on the AHB.
124 * (iii) TXn min size = 16 words. (n : Transmit FIFO index)
125 * (iv) When a TxFIFO is not used, the Configuration should be as follows:
126 * case 1 : n > m and Txn is not used (n,m : Transmit FIFO indexes)
127 * --> Txm can use the space allocated for Txn.
128 * case2 : n < m and Txn is not used (n,m : Transmit FIFO indexes)
129 * --> Txn should be configured with the minimum space of 16 words
130 * (v) The FIFO is used optimally when used TxFIFOs are allocated in the top
131 * of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones.

135 * FIFO Size Configuration in Host mode
137 * (i) Receive data FIFO size = (Largest Packet Size / 4) + 1 or
138 * 2x (Largest Packet Size / 4) + 1, If a
139 * high-bandwidth channel or multiple isochronous
140 * channels are enabled
142 * (ii) For the host nonperiodic Transmit FIFO is the largest maximum packet size
143 * for all supported nonperiodic OUT channels. Typically, a space
144 * corresponding to two Largest Packet Size is recommended.
146 * (iii) The minimum amount of RAM required for Host periodic Transmit FIFO is
147 * the largest maximum packet size for all supported periodic OUT channels.
148 * If there is at least one High Bandwidth Isochronous OUT endpoint,
149 * then the space must be at least two times the maximum packet size for
