27 / 40 page  [AK4160] MS1313-E-01 2011/11 - 27 - Charge Current Register (CCn: n=0~15) Address 0x45-0x54 (W/R) Default 0x00 Description D7 D6 D5 D4 D3 D2 D1 D0 Charge Current Reserved Reserved CCn[5] CCn[4] CCn[3] CCn[2] CCn[1] CCn[0] Bits Name Description D7-D6 Reserved Reserved: This bit should be written “0”. D5-D0 CCn The charge current from the terminal CSn is set. 0.556 x CCn x VDD [uA] When automatic setting is valid (Addr 0x5F ACE bit = “1”), these bits are updated after the setting is completed. This value may not be correct during the automatic setting. These bits can not be changed by the serial I/F in run-mode. Charge Time Register (CTn: n=0, 2, 4, 6, 8, 10, 12, 14) Address 0x55-0x5C (W/R) Default 0x00 Description D7 D6 D5 D4 D3 D2 D1 D0 Charge Time Reserved CTn+1[2] CTn+1[1] CTn+1[0] Reserved CTn[2] CTn[1] CTn[0] Bits Name Description D7,D3 Reserved Reserved: This bit should be written “0”. D6-D4 D2-D0 CTn+1 CTn The charge time at the terminal CSn is set. 0.25us~32us = 0.25us x 2CTn When automatic setting is valid (Addr 0x5F ACE bit = “1”), these bits are updated after the setting is completed. This value may not be correct during the automatic setting. These bits can not be changed by the serial I/F in run-mode. GPIO Date Register (GPDT) Address 0x5D (W/R) Default 0x00 Description D7 D6 D5 D4 D3 D2 D1 D0 GPIO Data Register GPDT[7] GPDT[6] GPDT[5] GPDT[4] GPDT[3] GPDT[2] GPDT[1] GPDT[0] Bits Name Description D7-D0 GPDT GPIO Output Data Setting When the touch status is output (SRC1-0 bits = “01”, “10”, “11”), the output is valid according to GPDT7-0 bits = “1”. GPIO Enable Register (GPEN) Address 0x5E (W/R) Default 0x00 Description D7 D6 D5 D4 D3 D2 D1 D0 GPIO Enable Register GPEN[7] GPEN[6] GPEN[5] GPEN[4] GPEN[3] GPEN[2] GPEN[1] GPEN[0] Bits Name Description D7-D0 GPEN GPIO Enable Exclusive control is provided for the sense terminal select (SCC Register NCH bit). When a pin has already been selected as GPIO, the sense terminal selection is invalid. |
