Endpoint Interrupt Status Register USR (Address 0X1B)
The USR (USB endpoint interrupt status register) register is used to indicate which endpoint is accessed and to select
the serial bus (PS2 or USB) and A/D converter operation modes. The endpoint request flags (EP0IF, EP1IF) are used
to indicate which endpoints are accessed. If an endpoint is accessed, the related endpoint request flag will be set to 1
and a USB interrupt will occur (If a USB interrupt is enabled and the stack is not full). When the active endpoint request
flag is served, the endpoint request flag has to be cleared to 0 .

PEC0
R/W
EP0IF
When set to 1 , indicates an endpoint 0 interrupt event.
Must wait for the MCU to process the interrupt event and
clear this bit by firmware. This bit must be 0 , then the
next interrupt event will be processed. Default value is
0 .
1
PEC1
R/W
EP1IF
When set to 1 , indicates an endpoint 1 interrupt event.
Must wait for the MCU to process the interrupt event,
then clear this bit by firmware. This bit must be 0 , then
the next interrupt event will be processed. Default value
is 0 .
2
PEC2
R/W
Reserved bit, set to 0
3
PEC3
R/W
Reserved bit, set to 0
4
PEC4
R/W
SELPS2
When set to 1 , indicates that the chip is working under
PS2 mode. Default value is 0 .
5
PEC5
R/W
SELUSB
When set to 1 , indicates that the chip is working under
USB mode. Default value is 0.
6
PEC6
R/W
VRSEL
When set to 0 , indicates the reference voltage of the
8-bit ADC from the external input pin. When set to 1 ,
indicates that the reference voltage is from the internal
power line. Default value is 1 .
7
PEC7
R/W
USB_flag
This flag is used to show that the MCU is in USB mode
(Bit=1). This bit is R/W by FW and will be cleared to zero
after power-on reset. The default is 0 .
