32. USB 2.0 Host/Function Module (USBc)
IDPSINKE0 Bit (D+ Pin 0.6 V Input Detection (Comparator and Sink) Control)
With this bit set to 1, when the function controller selected, the USB module detects whether VDMSRC (0.6 V) that is
output from the function to D– is connected to the function’s D+ (DCP) via the host. When the host controller is selected,
the USB module detects whether VDPSRC (0.6 V) that is output from the function to D+ upon primary detection is
connected.
VDMSRCE0 Bit (D– Pin VDMSRC (0.6 V) Output Control)
With this bit set to 1, when the function controller selected, output is enabled upon secondary detection and VDMSRC
(0.6 V) is applied to D–. When the host controller is selected, output is enabled upon primary detection and VDMSRC
(0.6 V) is applied to D–.
CHGDETSTS0 Flag (D– Pin 0.6 V Input Detection Status Flag)
When the host controller is selected, this flag is set to 1 if the USB module detects whether VDMSRC (0.6 V) that is
output from the host to D– during primary detection is connected, or whether VDPSRC (0.6 V) that is output from the
function to D+ is connected to the function’s D– via the host.
PDDETSTS0 Flag (D+ Pin 0.6 V Input Detection Status Flag)
When the function controller is selected, this flag is set to 1 if the USB module detects whether VDMSRC (0.6 V) that is
output from the function to D– during secondary detection is connected to the function’s D+ (DCP) via the host.
When the host controller is selected, this bit is set to 1 if the USB module detects whether VDPSRC (0.6 V) that is output
from the function to D+ during primary detection is connected.
