Reset
VCCON (MVS) or RST (AES reset button, PST518B) -> NEO-B1 -> RESET (rises slowly, open collector in B1 ?) -> LSPC -> RESETP.
Notes:
- VCCON/RST depends on power supply or user input (main reset signal)
- NEO-B1 ANDs it with the watchdog reset signal (internal), or simply resets the watchdog timer to force a watchdog reset as long as VCCON/RST is low ?
- LSPC generates RESETP, which is a 1mclk long negative pulse sync'd to mclk falling edge triggered when RESET rises (used to sync clocks in NEO-D0)
RESET might be synchronized with a clock reaching B1 (1MB ? 6MB ?).
