address
0x5300 T16E_CA0 T16E Ch.0 Compare Data A Register
0x5302 T16E_CB0 T16E Ch.0 Compare Data B Register
0x5304 T16E_TC0 T16E Ch.0 Counter Data Register
0x5306 T16E_CTL0 T16E Ch.0 Control Register
0x5308 T16E_DF0 T16E Ch.0 Clock Division Ratio Select Register
0x530a T16E_IMSK0 T16E Ch.0 Interrupt Mask Register
0x530c T16E_IFLG0 T16E Ch.0 Interrupt Flag Register
The T16E registers are described in detail below. These are 16-bit registers.
note: When data is written to the registers, the "Reserved" bits must always be written as 0 and not 1.
T16e Ch.x Compare Data a Register (T16e_Cax)
Register name address Bit
T16e Ch.x 0x5300 D15–0 Ca[15:0]
Compare Data
(16 bits)
a Register
(T16e_Cax)
D[15:0] Ca[15:0]: Compare Data a
Sets compare data A. (Default: 0x0)
When CBUFEN/T16E_CTLx register is set to 0, this register can be used to directly read from or di-
rectly write to the compare data A register.
When CBUFEN is set to 1, data is read from and written to these registers via the compare data A buf-
fer. The buffer contents are loaded into the compare data A register when the counter is reset.
The data set is compared against the counter data, and a cause of compare A interrupt is generated if
the contents match. The timer output waveform changes at the same time (rises when INVOUT/T16E_
CTLx register = 0 or falls when INVOUT = 1). These processes do not affect the counter data or count
operations.
T16e Ch.x Compare Data B Register (T16e_CBx)
Register name address Bit
T16e Ch.x 0x5302 D15–0 CB[15:0]
Compare Data
(16 bits)
B Register
(T16e_CBx)
D[15:0] CB[15:0]: Compare Data B
Sets compare data B. (Default: 0x0)
When CBUFEN/T16E_CTLx register is set to 0, this register can be used to directly read from or di-
rectly write to the compare data B register.
When CBUFEN is set to 1, data is read from and written to these registers via the compare data B buf-
fer. The buffer contents are loaded into the compare data B register when the counter is reset.
The data set is compared against the counter data, and a cause of compare B interrupt is generated if
the contents match. The timer output waveform changes at the same time (falls when INVOUT/T16E_
CTLx register = 0 or rises when INVOUT = 1) and the counter is reset.
T16e Ch.x Counter Data Register (T16e_TCx)
Register name address Bit
T16e Ch.x 0x5304 D15–0 TC[15:0]
Counter Data (16 bits)
Register
(T16e_TCx)
D[15:0] TC[15:0]: Counter Data
Counter data can be read out. (Default: 0x0)
The counter value can also be set by writing data to this register.
