ENDPOINT MODE REGISTER (EPMODE)
EPMODE register contains the field which defines USB reset signal length and the field which defines the
direction of endpoints. EPMODE is located at FBH, Page 0 and read/write addressable.
Bit7
RESET_LENGTH[1].
Bit6
RESET_LENGTH[0] : This field defines the length of USB reset signal. The reset value is "00". MCU
can control USB reset length through this field. The definition is as below.
"00" : 22.4
s + α
"01" : 12.0
s + α
"10" : 6.0
s + α.
"11" : 4.0
s + α
(
α 0.66 s)
Bit5
Reserved.
Bit4
Reserved.
Bit3
Reserved.
Bit2
Reserved.
Bit1
ENDPOINT_MODE[1] : MCU can defines direction of interrupt transfer. If this value is "1" then endpoint
2 act as a OUT interrupt endpoint and if this value is "0" then endpoint 2 act as a IN interrupt endpoint.
The reset value is “0”.
Bit0
ENDPOINT_MODE[0] : MCU can defines direction of interrupt transfer. If this value is "1" then endpoint
1 act as a OUT interrupt endpoint and if this value is "0" then endpoint 1 act as a IN interrupt endpoint.
The reset value is “0”.
