User Flash Memory (UFM)
MachXO2-640/U and higher density devices provide a User Flash Memory block, which can be used for a variety of
applications including storing a portion of the configuration image, initializing EBRs, to store PROM data or, as a
general purpose user Flash memory. The UFM block connects to the device core through the embedded function
block WISHBONE interface. Users can also access the UFM block through the JTAG, I
device. The UFM block offers the following features:
TCCLKI
TCRSTN
TCIC
TCINT
TCOC
• Auto reload
• Time-stamping support on the input capture unit

Timer/Counter input clock signal
Register TC_RSTN_ENA is preloaded by configuration to always keep this pin enabled
Input capture trigger event, applicable for non-pwm modes with WISHBONE interface. If
enabled, a rising edge of this signal will be detected and synchronized to capture TC_CNT value
into TC_ICR for time-stamping.
Without WISHBONE – Can be used as overflow flag
With WISHBONE – Controlled by three IRQ registers
