PFR6 to PFR0 control output of the corresponding external bus interface and peripherals at the bit level.
Always set empty PFR bits to "0" except for the bits with
When the registers are used in single-chip mode, the external bus functions of PFR6, 8, 9, A, B1, B2, and C
cannot be used. Do not rewrite these registers. In addition, in single-chip mode, external bus function
output is disabled for the functions (A23-A16, WR1, SYSCLK, and CS3-CS0) that result from the initial
values set to "1" in PFR6, 8, 9, and A. (Use these registers as general-purpose ports.)
*: The MB91F353A/351A/352A/353A do not have PFRs that are PFRB1, PFRB2, PFRC, PFRG, and
PFRP. Also, the bit values of A23E, A22E, A21E, MCKE, PGE1, PGE3, PGE5, OTE1, OTE3, OTE4,
OTE5, OTE6, and OTE7 are invalid.
