6.8
Flash Boot Protection register
Sec<i>_Prot:
1: Secondary Flash memory Sector <i> is write protected.
0: Secondary Flash memory Sector <i> is not write protected.
Security_Bit:
0: Security bit in device has not been set.
1: Security bit in device has been set.
6.9
Page register
This register configures the page input to PLD.
Default value is PGR7-PGR0=0.
6.10
PMMR0 register
The bits of this register are cleared to zero following Power-up. Subsequent Reset (RESET)
pulses do not clear the registers.
APD Enable:
0: Automatic power-down (APD) is disabled.
1: Automatic power-down (APD) is enabled.
PLD Turbo:
0: PLD Turbo is on.
1: PLD Turbo is off, saving power.
