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 13-100 | |
| Enable writing to register bits UART_MCR[7-5] | UART_EFR[4] ENHANCED_EN | 1 |
| Configure mode A | see Table 13-100 | 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 13-100 | |
| Set the submode MSR_SPR | UART_EFR[4] ENHANCED_EN | 0 |
| Second option: configure the submode MSR_SPR | ||
| Configure mode B | see Table 13-100 | |
| 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 13-100 | |
| Set the submode XOFF | UART_EFR[4] ENHANCED_EN | 0 |
