Table 31-13. Command Byte Bit Encoding
Pulses of CLKI and in the following command sequences are assumed to be at least
250 ns wide unless otherwise noted.
The following algorithm puts the device in parallel programming mode:
1. Apply 3.3V between DEVDD and DVSS.
2. Set RSTN to 0 and TST to 0.
3. Set the Prog_enable pins listed in
4. Set TST to 1. TST can be set high any time before but not after the rising edge of
5. Set RSTN to 1. Any activity on Prog_enable pins within 100 ns after RSTN is set to 1
6. Wait at least 50 µs before sending a command.
