523 / 818 page ![]() Section 13 Smart Card Interface Rev.3.00 Mar. 26, 2007 Page 481 of 772 REJ09B0355-0300 13.2.4 Serial Control Register (SCR) Bit : 76 543210 TIE RIE TE RE MPIE TEIE CKE1 CKE0 Initial value : 00 000000 R/W : R/W R/W R/W R/W R/W R/W R/W R/W In smart card interface mode, the function of bits 1 and 0 of SCR changes when bit 7 of the serial mode register (SMR) is set to 1. Bits 7 to 2—Operate in the same way as for the normal SCI. For details, see section 12.2.6, Serial Control Register (SCR). Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0): These bits are used to select the SCI clock source and enable or disable clock output from the SCK pin. In smart card interface mode, in addition to the normal switching between clock output enabling and disabling, the clock output can be specified as to be fixed high or low. SCMR SMR SCR Setting SMIF C/ A AA A, GM CKE1 CKE0 SCK Pin Function 0 See the SCI 1 0 0 0 Operates as port I/O pin 1 0 0 1 Outputs clock as SCK output pin 1 1 0 0 Operates as SCK output pin, with output fixed low 1 1 0 1 Outputs clock as SCK output pin 1 1 1 0 Operates as SCK output pin, with output fixed high 1 1 1 1 Outputs clock as SCK output pin |
