RM0090 USB on-the-go high-speed (OTG_HS)
OTG_HS device IN endpoint FIFO empty interrupt mask register:
(OTG_HS_DIEPEMPMSK)
Address offset: 0x834
Reset value: 0x0000 0000
This register is used to control the IN endpoint FIFO empty interrupt generation
(TXFE_OTG_HS_DIEPINTx).

Bits 31:16 Reserved, must be kept at reset value.
Bits 15:0 INEPTXFEM: IN EP Tx FIFO empty interrupt mask bits
These bits act as mask bits for OTG_HS_DIEPINTx.
TXFE interrupt one bit per IN endpoint:
Bit 0 for IN endpoint 0, bit 15 for IN endpoint 15
0: Masked interrupt
1: Unmasked interrupt
