User manual
9.6.12 UART Auto-baud Control Register (U0ACR - 0x4000 8020)
9.6.11 UART Scratch Pad Register (U0SCR - 0x4000 801C)
Table 102. UART Modem Status Register (U0MSR - address 0x4000 8018) bit description
The U0SCR has no effect on the UART operation. This register can be written and/or read
at user’s discretion. There is no provision in the interrupt interface that would indicate to
the host that a read or write of the U0SCR has occurred.
Table 103. UART Scratch Pad Register (U0SCR - address 0x4000 8014) bit description
The UART Auto-baud Control Register (U0ACR) controls the process of measuring the
incoming clock/data rate for the baud rate generation and can be read and written at
user’s discretion.
