13.9 Extended Control Register (ECR, at "base address + 7")
This 8-bit register provides control settings for Smart Card interface.
Bit 7 – 6: These two bits (BASESEL1 and BASESEL0 respectively) select internal sampling clock
Bit 5 – 4: These two bits (CLKSEL1 and CLKSEL0 respectively) select frequency of SCCLK.
Bit 3: CLKSTPH. This bit determines SCCLK stuck at high or low after CLKSTP is set to 1. SCCLK
Bit 2: CLKSTP. Setting this bit to 1 will stop SCCLK.
Bit 1: SCDIR. This bit determine direction of SCIO pin. SCIO serves as an input port if SCDIR is 1. It
Bit 0: WRST. Writing a 1 to this bit issues a warm reset to IC card. It is self-cleared after writing a 1.
