14.3.2
Disabling
Provided that the NVM enable bit has been cleared, the TPI is automatically disabled if the RESET pin is released
to inactive high state or, alternatively, if V
HV is no longer applied to the RESET pin.
If the NVM enable bit is not cleared a power down is required to exit TPI programming mode.
14.3.3
Frame Format
The TPI physical layer supports a fixed frame format. A frame consists of one character, eight bits in length, and
one start bit, a parity bit and two stop bits. Data is transferred with the least significant bit first.
Figure 14-4. Serial frame format.
Symbols used in Figure 14-4:
ST:
Start bit (always low)
D0-D7: Data bits (least significant bit sent first)
P:
Parity bit (using even parity)
SP1:
Stop bit 1 (always high)
SP2:
Stop bit 2 (always high)
14.3.4
Parity Bit Calculation
The parity bit is always calculated using even parity. The value of the bit is calculated by doing an exclusive-or of
all the data bits, as follows:
P = D0
D1 D2 D3 D4 D5 D6 D7 0
where:
P:
Parity bit using even parity
D0-D7:
Data bits of the character
14.3.5
Supported Characters
The BREAK character is equal to a 12 bit long low level. It can be extended beyond a bit-length of 12.
Figure 14-5. Supported characters.
14.3.6
Operation
The TPI physical layer operates synchronously on the TPICLK provided by the external programmer. The depen-
dency between the clock edges and data sampling or data change is shown in Figure 14-6. Data is changed at
falling edges and sampled at rising edges.
