BOOTSTRAP MODE
Bootloader mode is entered upon the rising edge of RESET if the IRQ/VPP pin is
at VTST and the PB0 pin is at logic zero. The Bootloader program is masked in the
ROM area from $0E00 to $0FEF. This program handles copying of user code from
an external EPROM into the on-chip EPROM. The bootload function has to be
done from an external EPROM. The bootloader performs one programming pass
at 1ms per byte then does a verify pass.
The user code must be a one-to-one correspondence with the internal EPROM
addresses.
B.5
EPROM PROGRAMMING
Programming the on-chip EPROM is achieved by using the Program Control Reg-
ister located at address $3E.
Please contact Motorola for programming board availability.
B.5.1 EPROM Program Control Register (PCR)
This register is provided for programming the on-chip EPROM in the
MC68HC705J5A.
MORON – Mask Option Register ON
0 =
Disable programming to Mask Option Register ($0200 & $0201)
1 =
Enable programming to Mask Option Register ($0200 & $0201)
ELAT – EPROM LATch control
0 =
EPROM address and data bus congured for normal reads
1 =
EPROM address and data bus congured for programming (writes
to EPROM cause address and data to be latched). EPROM is in
programming mode and cannot be read if ELAT is 1. This bit should
not be set when no programming voltage is applied to the Vpp pin.
PGM – EPROM ProGraM command
0 =
Programming power is switched OFF from EPROM array.
1 =
Programming power is switched ON to EPROM array. If ELAT
≠ 1,
then PGM = 0.
Bits [7:3] – Reserved
These are reserved bits and should remain zero.
