PRIVF, 08h[0Bh] Privilege Flag Register (8 bits)
Initialization This register is cleared to 00h on all forms of reset .
Access Unrestricted direct read/write .
PRIVF.3 to PRIVF.0 Reserved . All reads return 0 .
PRIVF.4 (PULRF) Protected User Loader Read Interrupt Flag. The interrupt flag is set to 1 if code
attempts/requests to read user loader memory when PULR = 0 . Once set, this flag can
only be cleared by software or by reset .
PRIVF.5 (PULWF) Protected User Loader Write Interrupt Flag. The interrupt flag is set to 1 if code
attempts/requests to write user loader memory when PULW = 0 . Once set, this flag can
only be cleared by software or by reset .
PRIVF.6 (PSYRF) Protected System Read Interrupt Flag. The interrupt flag is set to 1 if code attempts/
requests to read system memory when PSYR = 0 . Once set, this flag can only be cleared
by software or by reset .
PRIVF.7 (PSYWF) Protected System Write Interrupt Flag. The interrupt flag is set to 1 if code attempts/
requests to write system memory when PSYW = 0 . Once set, this flag can only be cleared
by software or by reset .
