BOOT — Boot ROM Control
LOCK — Lock Registers
EMUL — Emulation Mode Control
ASPC[1:0] — ROM Array Space
WAIT[1:0] — Wait States Field
D-26
Reset state of BOOT is specified at mask time. This is a read-only bit.
Bootstrap operation is overridden if STOP = 1 at reset.
The reset state of LOCK is specified at mask time. If the reset state of the LOCK is
zero, it can be set once after reset to allow protection of the registers after initialization.
Once the LOCK bit is set, it cannot be cleared again until after a reset. LOCK protects
the ASPC and WAIT fields, as well as the ROMBAL and ROMBAH registers. ASPC,
ROMBAL and ROMBAH are also protected by the STOP bit.
Because the MC68HC16Z2 and the MC68HC16Z3 do not support ROM emulation
mode, this bit should never be set.
The ASPC field limits access to the SRAM array in microcontrollers that support sep-
arate user and supervisor operating modes. ASPC1 has no effect because the CPU16
operates in supervisor mode only. This bit may be read or written at any time. The
reset state of ASPC[1:0] is specified at mask time.
coding.
WAIT[1:0] specifies the number of wait states inserted by the MRM during ROM array
accesses. The reset state of WAIT[1:0] is user specified. The field can be written only
if LOCK = 0 and STOP = 1.
0 = ROM responds to bootstrap word locations during reset vector fetch.
1 = ROM does not respond to bootstrap word locations during reset vector fetch.
0 = Write lock disabled. Protected registers and fields can be written.
1 = Write lock enabled. Protected registers and fields cannot be written.
0 = Normal ROM operation
1 = Accesses to the ROM array are forced external, allowing memory selected by
the CSM pin to respond to the access.
