Program Memory Paging
Some devices have program memory sizes greater then 2K words, but the CALL and GOTO
instructions only have a 11-bit address range. This 11-bit address range allows a branch within
a 2K program memory page size. To allow CALL and GOTO instructions to address the entire 1K
program memory address range, there must be another two bits to specify the program memory
page. These paging bits come from the PCLATH<4:3> bits
GOTO instruction, the user must ensure that page bits (PCLATH<4:3>) are programmed so that
the desired program memory page is addressed
tions is executed, the entire 13-bit PC is POPed from the stack. Therefore, manipulation of the
PCLATH<4:3> is not required for the return instructions.
Example 6-1
assumes that PCLATH is saved and restored by the interrupt service routine (if interrupts are
used).
Example 6-1: Call of a Subroutine in Page1 from Page0

Section 6. Memory Organization
Devices with program memory sizes 2K words and less, ignore both paging bits
(PCLATH<4:3>), which are used to access program memory when more than one
page is available. The use of PCLATH<4:3> as general purpose read/write bits (for
these devices) is not recommended since this may affect upward compatibility with
future products.
Devices with program memory sizes between 2K words and 4K words, ignore the
paging bit (PCLATH<4>), which is used to access program memory pages 2 and 3
(1000h - 1FFFh). The use of PCLATH<4> as a general purpose read/write bit (for
these devices) is not recommended since this may affect upward compatibility with
future products.
