In-System Programming (ISP)

Using the JTAG signals on Port C, the entire PSD

Module device can be programmed or erased

without the use of the MCU. The primary Flash

memory can also be programmed in-system by

the MCU executing the programming algorithms

out of the secondary memory, or SRAM. The sec-

ondary memory can be programmed the same

way by executing out of the primary Flash memo-

ry. The PLD or other PSD Module Configuration

blocks can be programmed through the JTAG port

or a device programmer. Table 83 indicates which

programming methods can program different func-

tional blocks of the PSD Module.
