USB Endpoint x OUT WRT CNT Register (x = 1 to 4)
USB Endpoint x OUT WRT CNT register
The USB Endpoint x OUT MAXP register, shown in Figure 1.62, indicates the maximum packet size (MAXP) of EPx OUT
packet. The default values for all EPx OUT MAXP are 0 bytes.
The USB Endpoint x OUT WRT CNT Register, shown in Figure 1.63, contains the number of bytes of the current data set
in the OUT buffer. The USB FCU sets the value in the WRT_CNT Register after having successfully received a data set
from the host. The CPU reads the register to determine the number of bytes to be read from the buffer. The WRT_CNT
value does not decrement upon a CPU read of the FIFO Data Register. The WRT_CNT value is cleared (in double buffer
mode, the WRT_CNT value corresponding to the dataset being unloaded is cleared) when the CPU writes "1" to the
CLR_OUT_BUF_RDY bit of the OUT CSR or in AUTO_CLR mode, when the data set is unloaded from the buffer.
