pub const VI_FIELD_HZ_PAL: u64 = 50;Expand description
Nominal PAL field rate (R-6): PAL’s standard 50 Hz field cadence.
The counterpart to NTSC’s VI_FIELD_HZ — a documented broadcast standard
(N64brew Video Interface: NTSC ~60 Hz / PAL 50 Hz), not a fitted value, so it
is anchored the same way as the NTSC rate. Selected when the programmed field is
PAL-length (VI_V_TOTAL > 550, ~625 half-lines vs NTSC’s ~525), matching the
scan-out geometry’s ispal test. The interlace/serrate half-field quirk and the
exact H_TOTAL sub-field timing remain deferred under R-6.
