关于cc3200 host driver文档问题

1、host driver具体是运行在哪里，是cc3200中内嵌的cortex m4单片机还是外置单片机？

2、手册中提到的SPI/UART接口，指的是cc3200芯片管脚上引出的SPI和UART口吗？还是说是芯片内部cortex M4单片机通过了SPI/UART口和NWP连接？

Standard interface communication port:

• SPI – Supports standard 4-wire SPI: – 8-, 16-, or 32-bit word length – Default mode 0 (CPOL=0, CPHA=0) – SPI clock can be configured up to 20 Mbps. – CS is required. – Additional IRQ line is required for async operations.

• UART – Standard UART with hardware flow control (RTS/CTS) up to 3 Mbps. – The default baud rate is 115200 (8 bits, no parity, 1 start/stop bit).

Viki Shi：

1、内置MCU
2、引出的SPI及UART
