The prototypes for these functions are, as defined in
void sysreg_write(const int sysreg, const int value);
int sysreg_read(const int sysreg);
The parameter for these functions can be a member of the SysReg
sysreg
enumeration defined in
actual registers to a small constant defined as a user friendly name.
The SysReg enumeration has the following definitions:
/* General Register set */
sysreg_ASTAT
sysreg_SSTAT
sysreg_MSTAT
sysreg_ICNTL
sysreg_IMASK
sysreg_IRPTL
sysreg_DMPG1
sysreg_DMPG2
sysreg_IOPG
/* System Control Register set */
sysreg_B0
sysreg_B1
sysreg_B2
sysreg_B3
sysreg_B4
sysreg_B5
sysreg_B6
sysreg_B7
sysreg_SYSCTL = 0x11, // SYSCTL register
sysreg_CACTL
1-96
. This enumerations is used to map the
