Memory Configuration Timing
CONFIG is the operating state entered by asserting the CONFIG pin, and is used during parameter
configuration over the UART port. MEMORY CONFIG is a sub-state entered by the ‘M’ command where
the configuration memory is being programmed.
Note the limitation on maximum number of write cycles using the ‘M’ command, see Electrical
Specifications.
Configuration Mode Timing
Symbol
Value
Description / Note
t
RESET-IDLE
3.3 ms
Time from power up reset to module in normal. Idle mode
t
CONFIG-PROMPT
1 ms
Time from CONFIG pin is set low until prompt (“>”)
t
MEMORY-CONFIG
24 ms
In this period, the internal flash is programmed.
Do not reset, turn the module off,
or allow any power supply dips in this period as it may cause permanent error in
the Flash configuration memory. After 0xFF the host should wait for the ‘>’
prompt before any further action is done to ensure correct re-configuration.
t
Mode-CONFIG
46 ms
In this period, the internal flash is programmed.
Do not reset, turn the module off,
or allow any power supply dips in this period as it may cause permanent error in
the Flash configuration memory. After 0xFF the host should wait for the ‘>’
prompt before any further action is done to ensure correct re-configuration.
t
Command-Response
10 us
Time from end of command byte to start of response byte received on UART on
all commands except R, G, N and memory configuration commands.
t
CONFIG-IDLE
1 ms
Time from 'X' command until module in normal operation
