27/* Documentation on the old module's SetTimerCompare() and SetTimerMode() functions is difficult because SCE had replaced them
28 with a single function within later SDK versions: SetupHardTimer().

30 source = counter input (see below).
31 size = counter width (either 16 or 32).
32 prescale = counter input scale (e.g. for a prescale of 256 with a SYSCLOCK (36.8MHz) source, 36864000/256=144 ticks per msec)

34 Mode bits:
35 Value Bit(s) Description
36 0x0001 1 Enable gate
37 0x0002 2 Gate count mode
38 0x0004 3 Gate count mode
39 0x0008 4 Reset on target
40 0x0010 5 Interrupt on target
41 0x0020 6 Interrupt on overflow
42 0x0040 7 ??? (Repeat?)
43 0x0080 8 ??? (Clears interrupt bit on assertion?)
44 0x0100 9 "uses hblank on counters 1 and 3, and PSXCLOCK on counter 0"
45 0x0200 10 1/8 prescale (counters 0-2 only)
46 0x0400 11 Interrupt (status)
47 0x0800 12 Target (status)
48 0x1000 13 Overflow (status)
49 0x2000 14 1/8 prescale (counters 3-5 only)
50 0x4000 15 1/16 prescale
51 0x6000 14+15 1/256 prescale

53 Sources:
54 TC_SYSCLOCK 1 36.864MHz (MIPS R3000A in 36.864MHz IOP mode)
55 TC_PIXEL 2 13.5MHz (Note: regardless of the actual screen mode)
56 TC_HLINE 4 NTSC 15.73426573KHz (858 pixel clock), PAL 15.625KHz (864 pixel clock)
57 TC_HOLD 8 ??? (The FPS2BIOS code has this value too, but it isn't documented by Sony)
