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 secondary memory can be programmed the same way by executing out of the
primary Flash memory. The PLD or other PSD module configuration blocks can be
programmed through the JTAG port or a device programmer. Table
programming methods can program different functional blocks of the PSD module.
