Key Name Key Number Type Default Setting
PSKEY_BCSP_LM_TSHY 0x0412 uint16 250
Configure the BCSP link establishment protocol. This is only used if BCSP is used over the chip's UART.
uint16 tshy The Tshy value in milliseconds.
Key Name Key
Number
Type Default Setting
PSKEY_UART_DFU_CONFIG_STOP_BITS 0x0417 bool none
Configure the number of UART stop bits to use within the boot loader (DFU mode).
This field should be set to 0 (1 stop bit).
Key Name Key
Number
Type Default Setting
PSKEY_UART_DFU_CONFIG_PARITY_BIT 0x0418 uint16 none
Configure the UART parity to use within the boot loader (DFU mode).
This field should be set to 3 (even parity).
Key Name Key
Number
Type Default Setting
PSKEY_UART_DFU_CONFIG_FLOW_CTRL_EN 0x0419 bool none
Configure UART hardware flow control to use within the boot loader (DFU mode).
This field should be set to 0 (no hardware flow control).
Key Name Key
Number
Type Default Setting
PSKEY_UART_DFU_CONFIG_RTS_AUTO_EN 0x041a bool none
When UART data flows into the chip it passes from the wire, through a very small fixed buffer, then into
one of the chip's large (virtual memory/mmu) buffers. If this pskey is enabled then the chip deasserts RTS
to the host if the small fixed buffer (almost?) fills. This gives time for the mmu write logic to organise itself
when setting up to write to an mmu buffer.
In practice this field should be set to 0, since the small fixed buffer should never overflow.
Key Name Key Number Type Default Setting
PSKEY_UART_DFU_CONFIG_RTS 0x041b bool none
Configure the UART RTS output within the boot loader (DFU mode).
This field should be set to 0.
