This section describes how to set different register access submode.
Step | Register/Bit Field/Programming Model | Value |
---|---|---|
Configure the submode TCR_TLR | ||
Configure mode B | see Table 12-478 | |
Enable writing to register bits UART_MCR[7-5] | UART_EFR[4] ENHANCED_EN | 1 |
Configure mode A | see Table 12-478 | 0x1 |
Set the submode TCR_TLR | UART_MCR[6] TCR_TLR | 1 |
Step | Register/Bit Field/Programming Model | Value |
---|---|---|
First option: configure the submode MSR_SPR | ||
Configure mode B | see Table 12-478 | |
Set the submode MSR_SPR | UART_EFR[4] ENHANCED_EN | 0 |
Second option: configure the submode MSR_SPR | ||
Configure mode B | see Table 12-478 | |
Enable writing to register bits UART_MCR[7-5] | UART_EFR[4] ENHANCED_EN | 1 |
Set the submode MSR_SPR | UART_MCR[6] TCR_TLR | 0 |
Step | Register/Bit Field/Programming Model | Value |
---|---|---|
Configure of the XOFF | ||
Configure B | see Table 12-478 | |
Set the submode XOFF | UART_EFR[4] ENHANCED_EN | 0 |
