Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

P = Programmable bit

bit 13

Unimplemented

: Read as ‘1’

bit 12-11

WRT<1:0>:

Flash Memory Self-Write Protection bits

256 W Flash memory: PIC10(L)F320:

=Write protection off

=000h to 03Fh write-protected, 040h to 0FFh may be modified by PMCON control

=000h to 07Fh write-protected, 080h to 0FFh may be modified by PMCON control

=000h to 0FFh write-protected, no addresses may be modified by PMCON control

512 W Flash memory: PIC10(L)F322:

=Write protection off

=000h to 07Fh write-protected, 080h to 1FFh may be modified by PMCON control

=000h to 0FFh write-protected, 100h to 1FFh may be modified by PMCON control

=000h to 1FFh write-protected, no addresses may be modified by PMCON control

bit 10

BORV:

Brown-out Reset Voltage Selection bit

= Brown-out Reset Voltage (VBOR) set to 1.9V (PIC10LF320/322) or 2.4V (PIC10F320/322)

= Brown-out Reset Voltage (VBOR) set to 2.7V

bit 9

LPBOR:

Low-Power Brown-out Reset Enable bit

= Low-power Brown-out Reset is enabled

= Low-power Brown-out Reset is disabled

bit 8

LVP:

Low-Voltage Programming Enable bit

= Low-Voltage Programming enabled. MCLR/VPP pin function is MCLR.

= High Voltage on MCLR/VPP must be used for programming

bit 7

CP:

Code Protection bit(2)

= Program memory code protection is disabled

= Program memory code protection is enabled

bit 6

MCLRE:

MCLR/VPP Pin Function Select bit

If LVP bit = 1:

This bit is ignored.

If LVP bit = 0:

=MCLR/VPP pin function is MCLR; Weak pull-up enabled.

=MCLR/VPP pin function is digital input; MCLR internally disabled; Weak pull-up under control of

WPUA3 bit.

bit 5

PWRTE:

Power-up Timer Enable bit(1)

= PWRT disabled

= PWRT enabled

Note 1:

Enabling Brown-out Reset does not automatically enable Power-up Timer.

Once enabled, code-protect can only be disabled by bulk erasing the device.
