REGISTER 27-3: CW3: FLASH CONFIGURATION WORD 3 (CONTINUED)
bit 11-10
WUTSEL<1:0>: Voltage Regulator Standby Mode Wake-up Time Select bits
11 = Default regulator start-up time is used
01 = Fast regulator start-up time is used
x0 = Reserved; do not use
bit 9-8
SOSCSEL<1:0>: SOSC Selection Configuration bits
11 = Secondary oscillator is in Default (high drive strength) Oscillator mode
10 = Reserved; do not use
01 = Secondary oscillator is in Low-Power (low drive strength) Oscillator mode
00 = External clock (SCLKI) or Digital I/O mode⁽²⁾
bit 7-0
WPFP<7:0>: Write Protected Code Segment Boundary Page bits
Designates the 512 instruction words page boundary of the protected code segment.
If WPEND = 1:
Specifies the lower page boundary of the code-protected segment; the last page being the last
implemented page in the device.
If WPEND = 0:
Specifies the upper page boundary of the code-protected segment; Page 0 being the lower boundary.
Note 1: Unimplemented in 64-pin devices, maintain at ‘1’.
2: Ensure that the SCLKI pin is made a digital input while using this configuration, see Table 10-1.
3: Regardless of WPCFG status, if WPEND = 1 or if WPFP corresponds to the Configuration Word’s page,
the Configuration Word’s page is protected.
