REV. 1.4.0
1-CH FULL-SPEED USB UART
3.3.15
GPIO_SET Register Description (Read/Write)
Writing a ’1’ in this register drives the GPIO output high. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
3.3.16
GPIO_CLEAR Register Description (Read/Write)
Writing a ’1’ in this register drives the GPIO output low. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
3.3.17
GPIO_STATUS Register Description (Read-Only)
This register reports the current state of the GPIO pin.
3.4
UART Custom Registers
3.4.1
CUSTOM Register Description (Read/Write)
This register controls the bMaxPacketSize and enables the Wide mode functionality for the UART.
CUSTOM[0]: Enable wide mode
Logic 0 = Normal (7, 8 or 9 bit data) mode
Logic 1 = Wide mode - See “Section 1.5.1.1, Wide Mode Transmit” on page 7, “Section 1.5.2.3, Wide
mode receive operation with 7 or 8-bit data” on page 8
and “Section 1.5.2.4, Wide mode receive
operation with 9-bit data” on page 8.
CUSTOM[1]: Max Packet Size
Logic 0 = bMaxPacketSize = 64 bytes
Logic 1 = bMaxPacketSize = 63 bytes (this bit is automatically set to ’1’ if the XR21V1410 receives a
CDC_ACM USB command)
CUSTOM[7:2]: Reserved
These bits are reserved and should remain ’0’
3.4.2
LOW_LATENCY Register Description (Read/Write)
This register is automatically set to logic ’1’ for baud rates below 46921 bps, and can be manually set for baud
rates of 46921 bps and higher. This register enables the Low latency feature of the UART. Write to this
register following any desired baud rate setting change.
LOW_LATENCY[0]: Enable Low Latency mode
Logic 0 = Receive data is not forwarded from the Rx FIFO until bMaxPacketSize (64 bytes) or timeout (3
characters) has occurred.
Logic 1 = All data in the RX FIFO is provided to the USB host at the next BULK IN request irrespective of the
number of bytes in the FIFO.
LOW_LATENCY[7:1]: Reserved
These bits are reserved and should remain ’0’.
