Bit
Symbol
Description

ConnectPullDown_DS1
0 — disconnect built-in pull-down resistors on
OTG_DM1 and OTG_DP1
1 — connect built-in pull-down resistors on OTG_DM1
and OTG_DP1
Remark: This bit is effective only when port 1 is
configured as the host port (the OTGMODE pin is
HIGH, and the ID pin is LOW). When port 1 is
configured as the OTG port, (the OTGMODE pin is
LOW), the pull-down resistors on OTG_DM1 and
OTG_DP1 are controlled by the LOC_PULL_DN_DP
and LOC_PULL_DN_DM bits of the OtgControl
register.

SuspendClkNotStop
AnalogOCEnable
OneINT
0 — clock can be stopped when suspended
1 — clock cannot be stopped when suspended
0 — use external OC detection; digital input
1 — use on-chip OC detection; analog input
0 — HC interrupt routed to INT1, DC interrupt routed to
INT2
1 — HC and DC interrupts routed to INT1 only, INT2 is
unused

DACKMode
OneDMA
0 — normal operation; DACK1 is used with read and
write signals; power-up value
1 — reserved
0 — HC DMA request and acknowledge routed to
DREQ1 and DACK1, DC DMA request and
acknowledge routed to DREQ2 and DACK2
1 — HC and DC DMA requests and acknowledges
routed to DREQ1 and DACK1; DREQ2 and DACK2
unused

0
0 — INT1 interrupt is active LOW; power-up value
1 — INT1 interrupt is active HIGH
0 — INT1 interrupt is level-triggered; power-up value
1 — INT1 interrupt is edge-triggered
0 — power-up value
1 — global interrupt pin INT1 is enabled; this bit should
be used with the HcµPInterruptEnable register to
enable pin INT1
