Lattice Semiconductor
The block-level OE PT of each GLB is also tied to Block Input Enable (BIE) of that block. Hence, for a 256-macro-
cell device (with 16 blocks), each block's BIE signal is driven by block-level OE PT from each block.

On-Chip Oscillator and Timer
An internal oscillator is provided for use in miscellaneous housekeeping functions such as watchdog heartbeats,
digital de-glitch circuits and control state machines. The oscillator is disabled by default to save power. Figure 13
shows the block diagram of the oscillator and timer block.
