73 * The USB OTG HS Core supports two PHY interfaces:
74 * (i) An ULPI interface for the external High Speed PHY: the USB HS Core will
75 * operate in High speed mode
76 * (ii) An on-chip Full Speed PHY: the USB HS Core will operate in Full speed mode
77 *
78 * You can select the PHY to be used using one of these two defines:
79 * (i) USE_ULPI_PHY: if the USB OTG HS Core is to be used in High speed mode
80 * (ii) USE_EMBEDDED_PHY: if the USB OTG HS Core is to be used in Full speed mode
81 *
82 * Notes:
83 * - The USE_ULPI_PHY symbol is defined in the project compiler preprocessor as
84 * default PHY when HS core is used.
85 * - On STM322xG-EVAL and STM324xG-EVAL boards, only configuration(i) is available.
86 * Configuration (ii) need a different hardware, for more details refer to your
87 * STM32 device datasheet.

106 * FIFO Size Configuration in Device mode
107 *
108 * (i) Receive data FIFO size = RAM for setup packets +
109 * OUT endpoint control information +
110 * data OUT packets + miscellaneous
111 * Space = ONE 32-bits words
112 * --> RAM for setup packets = 10 spaces
113 * (n is the nbr of CTRL EPs the device core supports)
114 * --> OUT EP CTRL info = 1 space
115 * (one space for status information written to the FIFO along with each
116 * received packet)
117 * --> data OUT packets = (Largest Packet Size / 4) + 1 spaces
118 * (MINIMUM to receive packets)
119 * --> OR data OUT packets = at least 2*(Largest Packet Size / 4) + 1 spaces
120 * (if high-bandwidth EP is enabled or multiple isochronous EPs)
121 * --> miscellaneous = 1 space per OUT EP
122 * (one space for transfer complete status information also pushed to the
123 * FIFO with each endpoint's last packet)
124 *
125 * (ii)MINIMUM RAM space required for each IN EP Tx FIFO = MAX packet size for
126 * that particular IN EP. More space allocated in the IN EP Tx FIFO results
127 * in a better performance on the USB and can hide latencies on the AHB.
128 *
129 * (iii) TXn min size = 16 words. (n : Transmit FIFO index)
130 * (iv) When a TxFIFO is not used, the Configuration should be as follows:
131 * case 1 : n > m and Txn is not used (n,m : Transmit FIFO indexes)
132 * --> Txm can use the space allocated for Txn.
133 * case2 : n < m and Txn is not used (n,m : Transmit FIFO indexes)
134 * --> Txn should be configured with the minimum space of 16 words
135 * (v) The FIFO is used optimally when used TxFIFOs are allocated in the top
136 * of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones.
137 * (vi) In HS case 12 FIFO locations should be reserved for internal DMA registers
138 * so total FIFO size should be 1012 Only instead of 1024
