5.2
In ICSP mode, the 2-wire ICSP signals are time
multiplexed into the 2-wire to 4-wire block. The 2-wire
to 4-wire block then converts the signals to look like a
4-wire JTAG port to the TAP controller.
There are two possible modes of operation:
• 4-Phase ICSP
• 2-Phase ICSP
5.2.1
In 4-Phase ICSP mode, the TDI, TDO and TMS device
pins are multiplexed onto PGD in 4 clocks (see
Figure 5-4). The Least Significant bit (LSb) is shifted
first; and TDI and TMS are sampled on the falling edge

of PGC, while TDO is driven on the falling edge of PGC.
4-Phase mode is used for both read and write data
transfers.
5.2.2
In 2-Phase ICSP mode, the TMS and TDI device pins
are multiplexed into PGD in 2 clocks (see Figure 5-5).
The LSb is shifted first; and TDI and TMS are sampled
on the falling edge of PGC. There is no TDO output pro-
vided in this mode. The 2-Phase ICSP mode was
designed to accelerate 2-wire, write-only transactions.
Note:
The packet is not actually executed until the
first clock of the next packet.
To enter 2-Wire, 2-Phase ICSP mode, the
TDOEN bit (DDPCON<0>) must be set to
‘0’.
