The USB Host Resume Interrupt can only be used in this mode. If this interrupt is enabled,
the MCU will be interrupted when the USB Suspend signal is detected on USB Bus.
8.7 Interrupt
The EM78M612 has two interrupt vectors, one is in 0x0001, and the other is in 0x000A.
When an interrupt occurs while the MCU is running, it will jump to the interrupt vector
(0x0001 or 0x000A) and execute the instructions sequentially from interrupt vector. RF is the
interrupt status register that records the interrupt status in the relative flags/bits.
The interrupt condition could be one of the following
:
1. TCC Overflow
When the Timer Clock / Counter Register (R1) overflows, the
status flag RF[0] will be set to 1. Its interrupt vector is 0X0001.
2. EP0 Interrupt
When the UDC successfully received a setup transaction from
host to EndPoint0, the status flag RF[1] will be set to 1. Its
interrupt vector is 0X000A.
3. USB Suspend
When UDC detects a USB Suspend signal on USB bus, the
status flag RF[2] will be set to 1. Its interrupt vector is 0X000A.
4. USB Reset
When the UDC detects a USB Reset signal on USB bus, the
status flag RF[3] will be set to 1. Its interrupt vector is 0X000A.
5. USB Host Resume
When UDC detects that the USB bus has left the Suspend
condition, the status flag RF[4] will be set to 1. Its interrupt vector
is 0X000A.
6. Port 5 State Change
When the input signals in Port 5 changes, the status flag RF[5]
will be set to 1. Its interrupt vector is 0X0001.
7. High Pattern Detecting Interrupt Conditions If the Pattern Detecting Application function
is enabled, there will be three conditions with which interruption is
generated, and the status flag RF[6] is set to 1, Its interrupt vector
is 0X0001.
a) P.60 turns to low, and the Pattern Counter value bigger than
RA register value.
b) P.60 stays at high, and Pattern Counter value equal 0XFF.
c) P.60 turns to low and Pattern Counter value bigger than
0XFF.
