Note on using USB mode
Handling of SE0 signal in program (at receiving)
7534 group has the border line to detect as USB RESET or EOP
(End of Packet) on the width of SE0 (Single Ended 0).
A response apposite to a state of the device is expected.
The name of the following short words which is used in table 5 shows
as follow.
TKNE: Token interrupt enable (bit 6 of address 20
16
)
RSME: Resume interrupt enable (bit 5 of address 20
16
)
RSTE: USB reset interrupt enable (bit 4 of address 20
16
)
Spec: A response of the device requested by USB Specification 1.1
SIE: Hardware operation in 7534 group
F/W: Recommendation process in the program
FEOPE: False EOP error flag (bit 2 of address 19
16
)
RxPID: Token interrupt flag (bit 7 of address 1F
16
)

Function of USBPID control register 0 (address 0023

)
Bit 4 (STALL handshake control for OUT token) of this register is forcibly set by SIE under the special condition shown below.
Set condition; when PID of data packet = DATA0 (incorrect PID) in the status stage of the control read transfer.
SYNC field at reception
Normally, the SYNC field consists of “KJKJKJKK” (8 bits). However, as for SIE of the 7534 Group, when the low-order 6 bits are “KJKJKK”, it is
determined as SYNC.
