5.3.3 ISP Write Data Register
The Write Data Register (ISPWR) contains the data to be
written into the specified address. This register is undeter-
mined on Reset. This register can be accessed from either
flash program memory or Boot ROM. The Write Data register
must be maintained for the entire duration of the operation.

5.3.4 ISP Write Timing Register
The Write Timing Register (PGMTIM) is used to control the
width of the timing pulses for write and erase operations. The
value to be written into this register is dependent on the
frequency of CKI and is shown in Table 9 This register must
be written before any write or erase operation can take
place. It only needs to be loaded once, for each value of CKI
frequency. This register can be loaded from either flash
program memory or Boot ROM and must be maintained for
the entire duration of the operation. The MICROWIRE/PLUS
ISP routine that is resident in the boot ROM requires that this
Register be defined prior to any access to the Flash memory.
Refer to 5.7 MICROWIRE/PLUS ISPfor more information on
available ISP commands. On Reset, the PGMTIM register is
loaded with the value that corresponds to 10 MHz frequency
for CKI.
