/* Mod */Info: Performs the operation R1 Mod R2 12 bytes 7 cycles Unsigned Can operate in both processing modes Inline function Registers Destroyed: R1 R2 R3 MACHSH3 Hex: 6133321432150009010A3138
/* Arbitrary precision addition (unsigned) */Info: Performs the unsigned operation R1+R2 30 bytes 12*(# of bytes in operands)+4 cycles Inline function Registers Destroyed: R0 R1 R2 R3 R4 R5 R6 R7 SROther notes: Don't let R2 be greater than R1! R1 and R2 are pointers to the locations of the least significant bytes (highest addresses) of the operands in memory. R3 hold the number of bytes of the operands. If the operands differ in size, zero extend the shorter one. Must be greater than 0. R4 holds a pointer to the least significant byte (highest address) of the output location. The output location must have at most R3+1 bytes available for the answer.SH3 Hex: E000400455106620365E070233008D05246441104210470EAFF406292460

/* Linear Congruential Random Number Generator */R1 == R4*R1 mod R3Info: 40 bytes Subroutine, not an inline function. Other info: The routine automatically loads a constant seed. If you would like to seed it yourself, then set the least significant bit of R0 and put the seed in R1. The output is returned in R5. If you call this routine multiple times, then you are responsible for seeding the RNG in R1 with the results of the previous computation from R5.SH3 Hex: 40058F0D73173415D304010A6513335433550009050A3518000B000905F5E101AFF1D10002D63A86
